I'm not sure about it, as in whether I'd use it for me personally. But if I met you with your little boys, Felix and Rafferty, I think they were cool names. I much prefer the NN Raffy to the full name though. I've never actually heard of the name before... apart from the baby food "Rafferty's Garden" and I guess it hadn't occured to me it was a name.

Archie and Lincoln I'm not keen on as they're too popular. Archie is a top 50 name and Lincoln is in the top 100.
