I've never met a female
Rowan, nor heard of one IRL, so
Rowan for a boy is "normal" to me and I wouldn't consider it otherways.
Rowan Gabriel looks and sounds fine but it also feels as though it is missing something, sorry I can't be more specific, I guess because I'm not wild about either name it just lacks a lot of spark.
