What do you think of this name?

Marie • My fiance and I are expecting baby #2 our firstborn daughter passed away of SIDS last year so we are very excited and scared for this surprise pregnancy but we already love baby #2 too! R.I.P. Lily
I was going to name my baby Shye if it's a girl but my fiance just came up with the name Sevyn and i like it. Pronounced like the number 7. What do you guys think, Shye or Sevyn?
