Hello,
Thank you again for your help.
aghadowey,
Once in Scotland, their children married in the Church of Scotland so no real clues there. The only way I can think that I might find their religion is to check the poor relief records to see if they ever registered there.
Mary,
The spelling of Gilmer/ore has been consistently Gilmour once they arrived in Scotland and it is still used in middle names in our family today. It is good to know that there are other possibilities if I can get a bit further back in Ireland. I have their death certs and 27 looks right for Martha and not far off for William. It was a b. in law who registered him so he might not have been quite sure. Thanks for that.
Much appreciated,
Linda
