My great-great grandmother was Ellen or Helen McGarrity, (born in Ireland circa 1815, died in Uphall,Scotland, 1884) married Andrew Mooney (Co. Antrim, circa 1811, died Coatbridge, Scotland, 1879)in either Ireland or Scotland (I suspect the former).She was the daughter of Edward McGarrity and Rose O'Hagan, of whom I know nothing.She and Andrew Mooney had at least 4 children: Hugh, Rose, Helen and Andrew (my great-grandfather).
Ellen/Helen had at least one other sibling, Arthur McGarrity (born in Ireland c. 1804, died in Kirkintilloch, Scotlandin 1865), who married Jane McMillan. They had at least two children: Rose and Edward.
If anyone has any linkages, would be glad to hear from you. Would be especially interested in from where the McGarritys originated.
