Wm. Owens "Chesney" - cousin - son of Hiram Owens & Sarah - stepson of Jane Owens
He was the son of Hiram Owens of Montgomery Twp., Marion Co., OH and his first wife Sarah ("Satira") Sprague Owens. Together they had a daughter Minerva and this son William, who went by the nickname "Chesney." But Chesney's mother died about 1860 and Hiram Owens remarried to a woman named Jane Carey, and together they had a child named Eulalia (Ulalia) Augusta (who went by "Augusta"), Chesney's half sister. Then Chesney's father died about 1875, leaving Jane Carey Owens to care for her two step-children, her daughter, and Hiram's elderly mother, who lived into her 90s. Here are Census records, all from Montgomery Twp., Marion Co., OH, that document the course of events. William "Chesney" Owens' middle initial is hard to make out in the two records that give it, but there is no doubt about his identity.
1860 Census - OH, Marion Co., Montgomery Twp., La Rue PO: Hiram Owens, age 38, born in DE, "farmer"; with wife Sarah Owens, age 33, born in OH; and children all born in OH - Minerva, age 9; and William, age 4; and with live-in domestic servant Selena Warner.
1870 Census - OH, Marion Co., Montgomery Twp., La Rue PO: Hiram Owens, age 48, born in DE, "farmer"; with wife Jane Owens, age 38; and children both born in OH - son William H. (A?), age 14, and daughter U. A., age 6; plus an 82-year-old woman Margaret Owens, born in DE, clearly Hiram's mother.
By the 1880 Census, still in Montgomery Twp., Hiram no longer appears because Jane is "widowed," Margaret Owens is still in the household, now at the extraordinary age of 93, as are children William H. (or "A.") and daughter U. A., now listed as "Augusta.
