Seems it always works this way! When you least expect it, bamm! I found the two Inness families:
1900 INDIANA CENSUS JEFFERSON CO GRAHAM TWP
Series: T623 Roll: 380 Page: 11
I found William and Mary Inness and his brother Edward L. and Sophia D.Innes with their families; living next door to one another and next to the Spicers, who are also relative to the Grapers, thru marriage. And wouldn't you know it, the boys' mother is living with Edward and Sophia. She is born in Mass., in June of 1828. She, Mary A. S?ars?, recorded that she had had 12 children, but only 4 were still living. Her husband was born in New York; apparently he is deceased also. Perhaps she lost several children during the Civil War or something. This is as far as I will be going in this family, as it isn't a direct line, but I hope it helped.
