I am requesting for a look up if possible on a john LEITER who may have emigrated to Canada from Baltringen, Wurttemberg Germany around or between 1843-1854. I found john living in Buffalo, NY in 1870 I am looking for his boarder cross information and the dates when he may have crossed and with whom. John may have had a sister name Creszens. John was married in Canada to Mary NMN, his daughter Mary Leiter b. 1856. Thank you ahead of time if you can or will help.
