Cullen/Dunlavey
Hello Kim:
My G-mom's parents were John Gillen and Margaret Cullen (Kilcullen?). Their first child was baptised in Oct 1846, in County Sligo, which is well before your time period. The witnesses were Michael Gillen and a person named Dunlavey, with the first name missing. All records in U.S. show GG-mom maiden name Cullen. But, there is a strong possibility it is Kilcullen. My GG-parents emigrated to Baltimore, Maryland.
I stumbled across your email by accident. I do not know if there is a connection.
Regards,
Raymond Barley
