I am feeling your pain. I have a grandmother Rose (or Rosanna) Lanahan or Lenihan or Linahan or lenehan (I dont even know where to search with the name...
But she was born in 1838/39 in Ireland. I have been told (but can find no record) that she came to Boston at the age of 4. Next think I know is that she was marriend in NYC in 1853 to my grandfather Terrence Kinney (1828). They had 3 children in NY and then migrated to Warren County IL. Monmouth area. They bought land in IL in 1863. And then there are census and other documentation. But up until then I am at a loss. I do not know if her family stayed in NY. OR if they moved as well. But I do not have any family names. That is what is frustrating. I would love to share if I have anything that is useful. :) Teri Kinney-Bishop
