Here are examples of my work:

Traditional Names that are not too popular that start with a W, have a nickname, and the name should honor Travis and/or Connor.  This is for twins of unknown sex.  Last name is Clark.

Westley Travis Clark- Since you do not like Weston because it is too common and you couldn’t agree on Wesley, I present to you Westley as a possibility- a mixture of the two.  While it is not the most traditional name, it has a traditional feel to it being so close to Wesley.  Westley is currently ranked 680 in the top 1000 boys names.  It also can be shortened to the nicknames West or Wes depending on your preference.  There is also a reference to The Princess Bride in there if you are a fan of that. 

Winston Connor Clark- Winston is a traditional name that still has a modern feel with its similarity to Weston, without the popularity.  It can be shortened to Win for a fun nickname.  If you think Winston is too popular, a very similar name with the same nickname is Windsor.  Winston is currently ranked 398 in 2023 with 797 boys being named that.

Woodrow Travis Clark- Woodrow is an old classic name that is not currently popular, but has a great nickname with Woody.  Woodrow has not been in the top 1000 boys' names since 1983.

Walter Travis Clark- Walter used to be much more but has lost a lot of popularity in recent years.  It is a very traditional name and has the nickname Walt.  Walter is a more popular name coming in at 267 on the top 1000 boys names of 2023, but it is way down in popularity since the early 1900’s where it was in the top 100. 

Wellington Connor Clark- Wellington might not be the most traditional name, but it has a very traditional feel to it.  It is not popular either.  The nickname Wells is super cute!  Wellington is an old name and has not been in the top 1000 boys names since 1924. 

Wendy Constance Clark- Wendy is a very traditional classic name.  I chose Constance as it could be in honor of Connor.  Wendy Constance has a nice ring to it.  Wendy can have the nickname Wen.   Wendy has not been on the top 1000 girls names since 2018. 

Whitney Constance Clark- Whitney is a little bit more modern, but still very traditional in feel.  A nickname for Whitney could be Whit.  Whitney was popular in the past but has dropped to number 981 on the girls list.

Winifred Tracy Clark- Winifred is a very traditional name with some very modern feeling nicknames of Winnie or even Fred/Freddy.  Tracy is in honor of Travis.  Winifred is making a slight comeback coming in at 967 on the top girls names in 2023 after being off the list since 1965.

Wilhelmina Tracy Clark- Wilhelmina is a very traditional classic name with tons of nickname options.  Possible nicknames are Willa, Wilma, Mina, Billie, or even Minnie depending on what you like.  Wilhelmina is not too popular as it has not been in the top 1000 US girls names since 1952.

Winona Connor Clark- The least traditional of the girl names here that still has a very classic feel.  I paired this with Connor as I think that it can work as a girls name and in the middle name spot.  Winona can be shortened to Winnie or Nona.  While Winona is in the top 1000 girls names it comes in at 881 with just 305 girls being named this in 2023. 

Twin combinations:

• Woodrow Travis & Wilhelmina Tracy- Both have very old classic traditional feels with fun nicknames.  Woody and Willa or Woody and Minnie (though the second might be too Disney).
• Wellington Connor & Winifred Tracy- I love Wells & Winnie as a duo!
• Walter Travis & Wendy Constance- both very traditional names and Walt & Wen works well!
• Westley Travis & Winston Connor- West and Win is cute and both Travis & Connor are honored.
• Winona Connor & Whitney Constance- Both Winnie & Whit and Nona & Whit work and both are more modern traditional feeling names.

First Names only, 2-3 syllables, nicknames okay.  Nothing Biblical and no noun names.  Not too popular but not overly unique.  Must go with other children's names.

Boys

• Rory- This Irish name means Red King and sounds good with your other kids names.  It is unisex, which some of your kids' names are and it has a familiar but not too common feel to it coming in at 242 on the boys list in the U.S..  It also bookends the children with the R name to match Riley.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Rory.
• Ronan- Another Irish “R” name that would bookend with Riley.  The name means Little Seal.  It’s not too popular at 290 on the U.S. boys list.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Ronan.
• Grady- This name is also Irish and means Descendant of the Noble One.  It feels unique without being so uncommon it is strange, it comes in at 395 on the boys list.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Grady.
• Avery- This English name means Elf King and is a nice unisex name.  It goes well with the other names and again, is not too common, coming in at 241 on the U.S. boys list in 2023.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Avery.

Girls

• Rosalie- This is a French name meaning Beautiful Rose.  You could use the nickname Rose or Rosie as well for her.  You mentioned liking the name Lily but it being too popular so here is another floral name that fits well with your other children, bookending with Riley.  It is currently ranked 182 in the U.S. for girls' names.   Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Rosalie (Rosie).
• Robin- A solid English unisex name meaning Bright Fame.  Robin would bookend nicely with Riley and goes well with the other names as well.  It is also not too popular, but not too unique, coming in at 793 in the U.S. for girls names in 2023.   Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, & Robin.
• Bellamy- This is perhaps the most “unique” name on the list, coming in at 828 on the girls list.  It is a French name meaning Good Friend and also unisex.  The nickname Bella works really well with your other children.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, and Bellamy (Bella).
• Lorelei- This German name means Alluring Enchantress and leaves for some nickname possibilities with Lori or Rori.  Rori especially goes well with your other children.  Lorelei is currently 485 on the U.S. girls list.  Riley, Emma, Elizabeth (Ellie), Morgan, Mackenzie, & Lorelei (Rori).

Names that cannot be made into a nickname. Nothing too popular or too unique. Goes well with Bailey. Irish, Scottish, or English preferred. Meaning is not important.

Boys names:

• Brennan- I chose this name because it is an Irish name that goes well with Bailey.  It is not overly popular, but not unheard of.  It was not in the top 1000 boys names this past year, but was in the year prior. 
• Brooks- I chose this name because it is not an overly masculine English name, as Bailey is not overly masculine or feminine either.  It goes well with Bailey, but it is on the more popular side coming in at number 73 this past year in the top 1000 boys names.
• Kellen- I chose this because it is a good Irish name that is not super masculine or popular.  It came in at 919 on the top 1000 boys lists this past year.
• Tanner- I chose this name because it is an English name that is middling in popularity, coming in at 430 on the top 1000 boys list.  It would fit well with Bailey and would not be unheard of but not the name of every other child either. 
• Crosby- I chose this English name because it has a very neutral feel to me and seems to fit well with Bailey.  It was not in the top 1000 this past year, but was in the year prior.

Girls names:

• Neve- I chose this Irish name because it is not easily turned into a nickname and has a short, brisk style.  It has never been in the top 1000 girls names in the United States.
• Marlowe- I chose this English name because it has a fun, modern feel to it but also feels like it could fit both a child and an adult.  It is not overly feminine or popular, coming in at 836 on the top 1000 girls list.
• Greer- I chose this because it is a nice Scottish name with a short and sweet style.  It is not overly feminine and would pair well with Blair and Bailey.  It has never been in the top 1000 girls names in the United States.
• Sloane- I chose this name because it is a gender-neutral Irish name that has the same feel as Bailey.  It is a little more on the popular side coming in this past year at 151 on the top 1000 girls names list.
• Ainsley- I chose this English name because I felt it went well with your other names, though it does have a more feminine feel that the others on the list.  It is middling in popularity, so not too popular or too out there, coming in at 598 on the top 1000 girls names list.

Names that are the same in English and Spanish and are of both Spanish and Jewish ancestry.  Names that are not too common.  Meaning is very important.  Alice and Nathaniel are very important names to us.

• Esai- This name means “Gift” in Judeo-Spanish.  It is similar to many popular names today. 
• Natanael- This name means “God Has Given” in both Spanish and Hebrew and is similar to the name Nathaniel which you listed as one you’d like to honor.  It can be shortened to “Nate” or “Nat” as well. 
• Ariel- This name means “Lion of God” in both Spanish and Hebrew.  It can be shortened to “Ari” and also has a very modern feel to it. 
• Solomon- I chose this name because of its meaning, “Peaceful One” in Hebrew and its Spanish version Salomon means “Peace.”  It can also be shortened to Sol which is Spanish for Sun.
• Rafael- This name means “God is Merciful” and is the same in English and Spanish.  It is of both Hebrew and Spanish origin.  It can be shortened to Rafe as well. 
• Adela- I chose this name because it means Noble in both Spanish and Yiddish.  The name Alice means “from Nobility” and so this is a way to honor that name as well.  While this name is not unheard of, it has not been in the top 1000 girls names in the United States since 1957.
• Estraya- This name means Star in Judeo-Spanish and has a very lovely ring to it.  It also sounds like it would go very nicely with your other children’s names: Soralee, Khalil, and Estraya.  This name has never been in the top 1000 girls names in the United States.
• Viva- This name means Alive in Judeo-Spanish and has a vibrant feeling to it.  Similarly “Vida” means “Life” in Judeo-Spanish and is lovely as well.  Viva has not been in the top 1000 girls names in the United States since 1930, Vida however was ranked 966 this year.
• Cipiora- This name is one that will definitely stand out as different, but pretty.  It means “Bird” in Judeo-Spanish.  It has never been in the top 1000 girls names in the United States.
• Amada- This name means “Beloved” in Judeo-Spanish and has a familiar feel being so close to Amanda.  Since you are open to possible nicknames it can be shortened to “Amy” or even “Maddie” if you chose.  It has never been in the top 1000 girls names in the United States.
