The names Maria and Marie are used in some countries as middle names for boys. Example - the writer Rainer Maria Rilke (who's given name according to wikipedia was René Karl Wilhelm Johann Josef Maria Rilke).
This isn't really a case of a female name becoming male because they have two different origins but Bryce is feminine in Greek mythology(in the writings of Apollodorus she is one of the Danaids) while being a masculine name in English(although it's being used for girls now too). As I said, the two are not actually related.
