G'day Bill, I am also looking into the McErlain family tree. My ggrandmother was Sarah who married Edward Mullin. Edward was born in Ballymoney in 13/5/1870. They had 2 sons. Thomas (my grandad) and Edward. I don't have any info on Sarah at all and would appreciate to hear from you what you have. Please reply through my email. Many thanks for this.
We think the parish they were married in was St Aloysiuis in Springburn, Glasgow.If you have are looking for the same McErlain it would be great to hear from you.Many thanks.
