Thank you so very much for your interest and help. I found a death for Thomas Keenan in Fintona for 1863. This is somewhat confusing because Bridget was born in 1864 according to NY census and her gravestone in NY. Could one of these records be wrong? I have found Felix and James in Griffiths Valuation in COunty Donegal, Urney, ALt Lower. I can't find James or Jane Quinn in this area on the 1901 or 1911 census. I suppose I should be glad that I have found out as much as I have although I would love to go back further than this.
