Thank you for responding.The William Franklin Cottrell I am looking for was b. about 1804 in Ohio or in KY depending on which census record is examined. On 13 Apr 1826 WFC m. Margaret Ellington in Fayette Co., IL.Margaret d. in 1849 in McLean Co., IL. In 1850WFC m. Rachel Brock and the family moved to IA. Children of WFC & Margaret Ellington include: Michael,b. 1828 Mary, b. 9 Feb 1829, Funk's Grove, McLean Co., IL who m. William Randdolph, 1846 Susan, b. 1831, m. Justus Brock Casander, b. 1837, m. Henry Baker Harriet, b. ca.1841 Isaac Elias B., b. 1847, m. Cecelia F. Bender David
My Cottrell family left IA moving to Neosho Co., KS where WFC died 26 Jul 1876.
I agree that your Wm. F. Cottrell & WFC may be remotely related but relationship would be almost impossible to trace.
