In my Family Tree Maker data base, I have Samuel Kunz, born in 1805 in PA. Died Holmes County, OH.
His wife was also born Abt. 1805 in PA and she died in Ohio in 1842. So, she would have been only 37 when she died. He could have remarried by or before the 1860 census.
Looks like my ancestor, Henry Kuhns, would be Samuel's older brother. Henry was born in Northampton County, PA in 1798 and his occupation was that of a tailor. Although he purchased farm land in Ohio.
At one time Northampton county was very large, but it gradually was reduced in size, so that Lehigh County, PA became a separate county, where Herny Kuhns married Esther Ruff or Rough About 1820. Henry and Esther Kuhns are buried in Chestnut Hill Cemetery in Wayne County, Ohio.
