Rohan 1

Sounds too feminine to me although I know it’s a unisex name. It tends to be regional for whether it’s a predominantly boy's or girl's name. For example - It’s a top 100 name for girls at the moment in Scotland and is one of fastest rising names for girls. It doesn’t even feature on the top 100 boys list.

The name Rohan is a legitimate spelling of "Rowan" (pronounced simply "Row-an") and originated in Scotland (centuries before Lord of the Rings and totally unrelated to the Indian Sanskrit version pronounced "Ro-han"). Whereas Rowan can be masculine or feminine, Rohan is only masculine.
