Did you find your John Reany? I see a John listed in 1850 census in Orange County, New York with his wife and children. Possible older child was Gouveneur also listed in same county. Also found a John that immigrated arriving NY on June 21, 1830 from Ireland.
Wife was Jane and children listed in census were Mary, Robert, Ellen, John and Joseph. Don't see them listed in census after that year.
Any help or advice you can offer will be appreciated.
