Looking for any info or suggestions for great grandparents: He was James Duffy (b 1830, emig to US 1900 from Pound Street in Dunfanaghy, died US 1901). His brothers may have been John, Hugh, Patrick. One unknown sib or uncle was nabbed for counterfeiting.
She was Catherine McFadden (b circa 1830, died before 1901). She's from Tirlin, Creeslough, possibly Doe Parish. Her father was Anthony McFadden, no idea on mother. Two of her brothers were Dennis and Patrick (who married Rose Gallagher).
James and Catherine married circa 1850. They had Michael (b 1850?), Maurice (b 1864) Bridget (b 1865?), John (b 1865?), James (1867), Mary Anne (b 1871), Catherine (b 1873), Charles (b 1875).
Any help would be greatly appreciated!
