Sue, I have Joseph Henthorn b. 1812, OH, d. 1852, Monroe County, OH. He married Ruth Ann Boughner abt 1830. Ruth Ann Boughner [d/o John Martain Boughner & Sarah Catherine (Boughner)] was born abt 1810 in PA. It's more than likely she also died in Monroe Co, OH...and I think I might be able to find that information. My mother and grandmother went to Monroe County and I think they got a transcription of her grave. I can ask my mother today.I got the information on Joseph Henthorn from the book "Henthorns: A Tip of the Iceberg." by Elizabeth Estlack Mullet and Helen Jane Estlack. It was printed in 1990. If you would like more information, please email me at EButcher@nc.rr.com.
