Hi, My Dunkin ancestors also lived in Washington Co, Pa and are found in the 1790 census, they then moved to Adams Co, Ohio and where there by 1810-1830. At that time they moved on to Fountain Co, Indiana. I strongly suspect they got there suppliestogether and loaded them on to flatboats at Maysville, Kentucky. they then went down the Ohio, up the Wabash to what is now Independence Station Indiana...they named it Maysville, Indiana then. I have found some Kerr folks mentioned in the History of Fountain County... Samuel Kerr is mentioned as being the son of a Josiah Kerr. One of them was the "respectable preacher" in the christian church.. It also states that Samu el Kerr son of Josiah Kerr is one of the most susccessfull farmers and largest land owners. Barzillai Ker deceased some two years since, one of Richland's (township) greatest men. It seems to me that I remember seeing some Kerr headstones at the Salem Cemetary in Davis township Fountain County, Indinana when I visited there. I don't know if these folks are yours .
