[name_m]Just[/name_m] happened to be on Twitter where a discussion about the name [name_f]Siobhan[/name_f] was being held. I asked if it, based on what Nameberry had used for meaning, was the [name_u]Irish[/name_u] equivalent to Joan/Joanne, and I got several different answers. Some said no, one said it could be translated that way, and one said that it could be better used as an equivalent to [name_f]Susan[/name_f].
Are any of these correct?
