Please tell me you opinions on my baby girl names

[fairyteepee]

Trying to think of some new baby girl names, please tell me you opinion.

Silver
Thora
Tabitha
Taffetta

Thora and Tabitha are both nice.

Silver and Taffeta pretty awful....especially with Tilly

Taff n Till
Sil n Till

My niece is called Sylva and I think it's really pretty. Not so sure about Taffetta but like Tabitha

Silver is not 'a version' of Sylvia or Sylvie.
It's a metal.
Sylvia (etc) come from a Latin word meaning 'woodland' or 'forest'. So 'Sylvia' = lady of the trees'.
