My John Lehman was born abt 1830 and was married to Philipina Jung. This is the only marriage I am aware of. The 1851 Census shows a child born Dec 1, 1851 named Lorenz (Lawrence) who was my gg-grandfather married to Catherine Frances Winter and then to Susan Schick, both in W. Branch. The Ont. records show John and Philipina had three children by 1853 and then drop out of the records. E-mail me if this helps or if you might need more information.
