I don't think that, after all these years, the question has been answered. Can we please re-address?
Jacob Leffler , Jr. - b. ca. 1740 Hagarstown, MD - d. 1784 Donegal, Washington, PA. The "last battle of the Revolution" has been said to have been fought at Rice's Fort in Sept 1782. Rice's Fort was in Donegal, Washington, PA.
To whom was Jacob Leffler married? 2 good authorities have his only wife as 2 different women from 2 different families.
Raymond Bell Anthologies has Jacob's only wife as Elizabeth Hewitt (1745-1823) dau. of Franz Carl Huyett. Included is the account of Jacob Leffler, Jr., one of the defenders of Rice's Fort. Elizabeth Hewitt married Jacob Leffler in Berks County early in 1762.
Bromwell Genealogies has Jacob's only wife as Catherine Miller
(This may be the Catherine Miller, dau of Jacob Miller (Rice's Fort).
Both are a widow before remarrying to the Rev. Jasper Simler in or near 1786!
Also, there is Boyd Crumrine, "History of Washington County, Pennsylvania with Biographical Sketches of Many of Its Pioneers and Prominent Men" (Philadelphia: L. H. Leverts & Co., 1882).
There was a Catharine Leffler who m. Peter Miller, son of Jacob Miller. Also, of Rice's Fort.
I have Elizabeth Hewitt in my Tree because I believe the Bell research is most accurate but I can be otherwise convinced ~
