I believe that Catherine was a sister of my GG Grandfather James. James and his parents Patrick Lanahan and Susan Crosby were born in Ireland. Have yet to figure out the Ireland to Savannah to Philadelphia migration. Catherine ( Kate ) McKeown on the 1880 census in Philadelphia is listed as being born in Savannah. Catherine and William lived at 138 Otter St in Philly. Otter St is now know as Wildey St. Many of the old houses are now gone. I have been trying to locate Lanahan family connections. Looks like we may have a connection. Regards, Tom Duffin
