Great to hear from you. I was at the reunion this year. I think my mom was the only one there that had the last name McGann. There were lots of Manleys there. It was great to meet them all. Mom tries to go every year.
Hopefully with continued sifting, we can come up with a home town in Ireland. There are other McGanns that settled in Maryland. Several of them list a common county of origin,County Roscommon, Ireland. Some of them came over about the same time as our McGanns. I live in Baltimore. I go to the Maryland Archive about once a month. I recently discovered they have the church records for St Michael's in Frostburg. Have you seen them? I plan to check them out the next time I go. Send me your contact info and I will let you know what I find.
