Stephanie, It would help others to help you if you could at least tell us what state you think Margaret Leffler was born in or what your great grandmother's maiden name was. I research Lefflers in Ohio (especially Fairfield and Hocking Counties) and I've come across the Friend surname many times there. In fact, there is a gal who works in the Fairfield County Genealogy Society in Lancaster, Ohio with the last name of Friend. You might call them or check out their website. Just Google for it.
