A friend of mine who analyzed the same picture said the man is most likely in his late 30s or early 40s. He was definitely one who worked with his hands. The photo is most certainly 1860s era.
Do you have any information on a James T. Trisler (or anyone who could possibly be related), born about 1879 to a Sarah and Unknown Trisler, whom I presume was dead by the 1880 census? Sarah is in the 1850 Ohio census as an infant born to Justus and Elizabeth Wilson. The Wilsons lived very close (I presume, next door) to Norvel Jolley Jr. and his wife (Margarita?). In the 1860 census, Justus and Sarah Wilson disappear, along with Norvel Jolley Jr.'s wife. Norvel married Elizabeth Wilson in the late 1850s and had a number of children together, which the 1860 and 1870 censuses confirm. Sometime between 1860 and 1870, the Jolleys moved to Mason County, WV, from Gallia County, OH. Sarah shows up in the Jolley household in the 1880 census with two children and without a husband, Elizabeth B. and James T. Trisler (My great grandfather). She then marries a John H. McWhorter in 1882, Mason County, WV.
