When I became interested in genealogy, my first searches were in Church Registers of the late 1700s in Cork City. I was looking for the baptisms of my g. grandfather and his siblinlings and for the marriage of their parents. On my line I found nothing, but I found interesting entries which makes me wonder if Sheahan might have the same Irish language origin as I later discovered was the Irish form of my surname which my g. grandfather used in signing his name.
Now I am surprised how often in the earliest records I find the two names recorded in the same event – as Parent & Sponsor, or Spouse & Witness – and as near neighbours, eg in Spring Lane in Cork City.
I would welcome ‘feedback’ from any Sheahan, Sheehan or Hyde.
