My gggrandfather ,John Dillon, was born in Co Cavan in 1825, son of John Dillon and Mary Jane [nee Murphy] Dillon. He married Mary Welsh/Walsh in 1847 and came to the USA in 1850-51. They settled on a farm in Sullivan Co, NY , His obit states that his family on both sides was prominently involved in the Revolution of 1798 . A tribute written upon his death states that he gave up his legacy and his wife's dowery when he left Ireland due to trying times. ........and that's it !! That's all I know about my ancestor. Any help or leads will be greatly appreciated. I have a photo of the old gent and will be glad to share it with anyone who would like to see him.
