I am looking for information regarding my great great grandfather, Lawrence P. Lanahan he was born March 19, 1866 in Ohio to Michael Lanahan and Hanorah Blake Lanahan. Lawrence's death certificate indicates that both of his parents were born in Ireland but does not name a county. Lawrence married Sarah Elizabeth Miller in Louisville, Jefferson County, KY on March 25, 1884. Lawrence was an engineer for Southern Railroad and died on January 18, 1926. If anyone has any information that can help me trace the Lanahan and Blake lines I would really appreciate it.
