i dont know if you are still looking at this but i just stumbled across this website while browsing the Mailey name. My family is also living in Australia - we are in WA but we are originally from Ireland - my parents moved over when we were younger. Funnily enough 1 other Mailey family in WA is my dad's brother. We originate from Belfast in Ireland. Just thought id let you know as it is a very unusual name - especially in Australia! The other branch of Maileys in WA arent related to us, they have been in contact a few years ago.
