Help with characters names.?

Im currently in the early drafts of writing a sort of family based drama novel. The basic settings a family moves from a small village in Ireland with there youngsters to london. as the children grow the parents are shocked at how much city life corrupts them. two of the children(or adults) are brothers..only a year apart (one being 22, the other 21) the eldest is volatile and has no empathy, violence is his only option although it is possible for him to show a more loving 'diamond in the rough' style personality. the younger one isn't an angel but comparatively should be and struggles to control his brother.(will ask a separate question about other family members!) well anyway need idea's for name's. the Family name is Morgan and the first two names that strike are Aidan and Sean.(I have an elder cousin named Aidan and he was very much the type of character i described earlier, also remember there parents are Irish) But im looking for peoples ideas and opinions. Greatly appreciate any help and feedback! (also a touch of help with parents names wouldnt go a miss lol)
