Jack, I have precious little information about the McGinns in Ireland. My grandfather Charles McGinn, migrated to Philadelphia about 1883. He was born September 1852 (not sure where), married in 1883 in Glasgow to Mary Ann O'Neill from Toombridge, Antrim. His father's name was Michael Maginn, married to Bridget Ward. Charles' siblings were John,Micahel, Elizabeth, Mary, Alice, Bridget. I have no other information about them. I contracted with a genealogy agency in Belfast to look in parish records in Tyrone (where, according to Giffith's Valuation, there were in 1850s losts of Maginns). Nothing turned up for my family. The search looked for Charles or Michael Maginn/McGinn and Bridget Ward in baptismal and marriage records in the Catholic parishes of Clogher, Drumragh and Termonmaguirk. A number of McGinns turned up, including some Johns, but no McGirrs or Macmahons. According to the Griffith's valuation, there were Michael Maginns also in Armagh,Galway, Monaghan and Dublin counties as well, but I haven't had the funds to go ahead with that search. My greatgrandfather, as well as his son were flax hecklers. Am I right in supposing the linen mills were in the North? What to do next?
