Sheryl - this is what I have in my database of Lefflers -- Margaret Leffler was the daughter of Henry Leffler and Elizabeth Kirstetter who lived in Northumberland County. Henry died about 1825 and Margaret is named in his will as is her husband. She and Jacob Schmitt had a son, Heinrich, born 17 Aug 1826 and baptized at Stone Valley Lutheran (I found this online). I have no further information on Margaret, but it is not one of the names I have gone back and done further research on. If you are a descendant, I am always willing to share information. I have more on some of Margaret's siblings. You can contact me direct at firstname.lastname@example.org
