Hello Shane, and thanks,
Yes, I think they were all C of I and Methodist. I can't find the records I need on the Irish Church records site.
Yes, I have tried the Representative Church Body Library (although some years ago).
I also have some information from the Wicklow Heritage Project.
I am thinking the earliest Richard must have been born elsewhere.
I'm pretty sure that some of the Cavan Blazers(?)in Canada were from Rathdrum and wonder if, maybe, his family were connected?
I have my tree (on public access) on Ancestry with more detail, if anyone wishes to browse (I think it's easy enough to find). The tree is called Many Leaves.
