Hello from a Guinan in Boston. My own family came from the Shannon Harbor area where Roscommon/Offaly meet. I've been doing some digging in this area, although there's only a few Guinans left there. Is there any way you would share any of the genealogy your family member compiled, or is it online anywhere? My gr gr grandfather was Patrick Guinan, married to Mary Furey. Anything sound familiar?
By the way, there's a gentleman named Sharmin ? (I can dig up his last name) who has been also looking for Guinans and Kennys in this area, and he mentioned the name Valentine as well. Perhaps you've read some of his postings?
Good luck to everyone in their searches. Dottie G. My email is firstname.lastname@example.org
