Help me name these kids’ families

I have five teenage characters, and I need desperate help coming up with their surnames and also their parents’ first names. I figured since Nameberry loves their CAF games it would be great to ask here. This story is set in America, by the way.

Liam - Lower class family. His parents are on the younger side, late 30’s to early 40’s. Race/nationality isn’t fully decided, but he’s probably white or African American.

Alex - Middle class. Half-jewish and half-asian family. Parents are in their mid 40’s. I think their last name will be Feldman, but I’m open to any other suggestions.

Maya - Middle to upper class. African American, possibly half-hispanic family. Parents are in their mid 40’s.

Connor and Sophie - These two are siblings, so they have the same last name and obviously the same parents. White, upper class family. WASPs. Parents are in their mid 40’s.

Please help me come up with their surnames and the first names of their parents! I want their parents’ names to fit their background while still sounding “right” with their children’s names. Same thing goes for their surnames, I really want them to flow well with the first names. No alliterative names, please!

liam barrow, parents are kayla barrow and ryan barrow

alex feldman, parents are david feldman and izumi feldman

maya williams-achebe, parents are valentina williams-achebe and tahir williams-achebe

connor and sophie walton, parents are edwin walton and allegra walton

Oh I absolutely love these! Is it alright if you could give some alternate suggestions for [name_u]Connor[/name_u] and Sophie’s parents? I plan on them interacting with Liam’s mom (Kayla) at some point and I just don’t really like both [name_f]Kayla[/name_f] and [name_f]Allegra[/name_f] ending in an “-ah” sound, and I’m not sure [name_m]Edwin[/name_m] and [name_f]Allegra[/name_f] fit much anyway. It’s a bit too regal, they’re upper class but they’re more like suburban WASPs. [name_f]Hope[/name_f] this isn’t a bother!

Bump!! I really need more help with this

oh ok of course !

connor and sophie walton (assuming the surname is okay?) parents are ashley walton and eric walton

[name_m]Smith[/name_m]
[name_u]Carter[/name_u]
[name_m]Lyons[/name_m] (I never see this surname anymore!)
McKenzie
[name_f]Makena[/name_f] (had a professor with that surname)
[name_u]Moreau[/name_u] (too [name_u]French[/name_u] probably)
Sallinger (don’t know if I spelled it correctly)
Singer
Moriarty
Michaels
[name_m]Williams[/name_m]
