Susan, We gotta quit meeting like this :) I've just been going through some of my Leffler notes and am wondering if this bit of info might mean something to you. I copied and pasted it from something on Ancestry.com. Sorry, I am terrible about documentation! I entitled it 'Early Leffler Marriages in Fairfield Co., OH':
Leffler, Betsey- Wenther Grove - Oct. 1819 Leffler, Jno.- Barbara Hiddlebaugh - Oct. 1818 Lefler, Magdalena - Jacob Ridemour - Jan. 1808 I know that Ridemour is supposed to be Ridenour)
I'm thinking there might be a connection between your Mary Leffler and this Magdalena Leffler and Jacob Ridenour. What do you think?
