Here's my two cents worth-my notes have Joseph Yarger b. 1801/5 Ohio, d. 15 Apr 1888, Wells Co., IN. He married Margaret Lewis 19 Aug 1830 in Adams Co., Ohio.She was b. 1805-1810 in VA. and had been apparently married to a Kessler previously-may have had one child, Mary Ann in 1825 by this marriage. Margaret d.29 Jan 1895 in Montpelier, Wells CO, OH.Susan was the 8th of 11 children of the second marriage to Yarger. Might try 1860 & 1880 census Nottingham Twp.,Wells CO., IN pg. 1000,& 139B. Thanks for your posting on Susan and Amaziah-I had not known this information before.
