LOVE this name! It's rare, and it's unquestionably masculine, but it also sounds smart and sweet and classy and strong and other such good things. You probably wouldn't get too many really strange looks over it, yet when people think about it, they'll likely realize that they've never before met or even heard of a Selwyn.
Selwyn Ward is an African-American actor who played T.J. Johnson (the second Red Turbo Ranger and the Blue Space Ranger) in the Power Rangers TV series.
