My Great Great Grandfather was Sewall Abbott. I've found this name listed as being born in Vermillion Co., Indiana. If anyone has information that would help me prove he is my ancestor, I would appreciate it. My Sewall Abbott married Mary McKinney, I believe in Illinois, but I'm not sure. Their son, Edward Ephraim was my GreatGrandfather and his daughter was my paternal Grandmother. She was born in Ia.
