I have a connection with McKeones from Waterford, originally from Kilfane in Kilkenny where William McKeon was a sub constable in the RIC 1832 to 1862.
Children that survived into adulthood: Catherine, married in Laois, William, married Ellen Thorpe in Waterford; James, joined RIC married Julia Huggins in Cork; Henry my mysteryman who was in the RIC for a short time, on the Goresbridge Census of 1872, possibly married a Margaret Carroll in 1887, after that no idea where he went.
