I have a record of a marriage between John J. LEACH and Catherine LEFFLER on 18 Aug 1839 in Butler County, OH. She would have been born about 1820 and I do not know his date of birth. In the 1840 census I find a J. J. Leach in Ross Twp., Butler County, OH with a male aged 5-10, a male aged 40-50, and a female aged 20-30. I do not find them in 1850. Does anyone have information on this couple? You can email me direct at ashortnote@psbnewton.com.
