We know little - only that Katherine Gormley was my husband's great-grandmother. From Strabane, County Tyrone. The Armagh posting above was from early in our ancestry search, and we thought our McGuirks were from Armagh.
The Cambridge connection is certainly a possibility, as our McGuirks went to Cambridge, Mass., where my husband's mother was born. So it's entirely possible that the Gormleys may have followed - or even preceded - them to that area.
