I can see Saphie: no doubt they pronounce
Sophia more like sahFIEa than sohFIEah. Wouldn't go that route myself, though.
I know a
Sophia, also chosen because her parents liked it. She is a redhead, and her nn (in the family, at least) is Fia, pronounced like Fire.
Tails would work as a nn for
Taylor; quite a cute idea.
