I like
Schuyler, because of actor
Michael J.
Fox named one of his twins
Schuyler Frances. Her twin's name is Aquinnah
Kathleen, older brother
Sam Michael and younger sister,
Esme Annabelle, which I also love. I find it fine on both genders. I like it more on a girl.
Skyler and
Skylar are cool as well, but I like
Schuyler more.
Im not a fan of
Schuyler Marcel, it doesn't sound well together, sorry.
I think
Schuyler would cause confusion and your child might have to spell it out, overall, I pronounce it like Sky-ler or Shy-ler.
