I'm interested in your Mary Decker - could be part of the family to mine. I have Joseph or possibly F. Joseph Decker b. 25 Jan 1779 in MD (I'm not totally sure about that yet) but he md Catherine Hartman b. bet 1790-1800 in Washington, PA. and they md in 1804 in Washington PA before moving to Guernsey Co. by the 1830s. I don't know whom his parents are or any siblings. -JO (Jeanne)
