I am looking for information about Cornelius Ryan born abt 1791-1800 in Ireland. He married Catharine born abt 1800-1802. They immagrated to the US between 1838 and 1850. They had at least four children who came with them.

John Ryan b. 1828 married Mary Ann, also born in Ireland
Thomas Ryan b. 1833
Ellen Ryan b. 1838
Jeremiah Ryan b. 1838

The family lived in Luzerne and Monroe counties. I am intersted in John Ryan. He had a son named James that ended up in Jefferson and Indiana counties.

Any information would be greatly appreciated.
Thanks,
Linda
