I have ancestors from Clonavaddy, Tyrone, named John Hagan and wife Ann/Anne Donnelly. Their children are: Bridget b:1865; Rose/Roseanne b: 1866 (m: Patrick Rogers); Henry b: 1867; Susan b: 1869 (m: Patrick McGovern); Patrick b: 1874; Theresa b: 1878 (m: William Saunders); and William John b: 1881.
As far as I can tell, the parents and all the children emigrated except Susan. William was back and forth between the US and Ireland after Susan's husband (Patrick) died. He had land he was trying to sell and could not. He lost his US citizenship due to not returning to the US after an extended stay in Ireland, due to not being able to sell his land. He also returned to Ireland to help his sister Susan with her young children.
