Am searching for William Henderson 1818-1880 & wife Hannah Dillon b. 12 Nov 1817 as listed in Some Quaker Families, page 175.Wm & Hannah in Vermilion Co. IL in 1850 with Sarah age 3 & Elam age 1.1856 in Dallas Co Iowa with son Lewis age 4 & Elom (sic) age 6. 1880 Census, Vasquez, Jefferson Colorado lists Hannah Henderson age 62 mother, Elam age 31 & Lewis age 28.William died Dec. 1880 (not proven). Lewis Henderson b. June 1852 IL was still in Denver Colorado in 1900, a blacksmith. The above seems to reflect that Hannah was still alive yet in 1880 and not connected with the 1832 date & Dover FBG Ohio mentioned on page 175. Anyone with further information about this family???
