Posting on genealogy.com message board for Richland Co., Ohio, from Mary Wojcik, 24 May 2001:
My grandmothers's notes include a drawing of Yankeetown School District No. 1. It is comprised of a 2 mile square of 16 families in Madison Township, Richland County, Ohio. SW corner shows Elihu Cornwall but no date of entrance to area. Others are dated 1816-1818. Elihu's daughter Sarah is my GG Grandmother. Following is only information I have:
"Elihu and wife Mary_____ came to Richland County in 1814 from Canada. They had seven daughters and three sons. Sons were Elihu, Elias and Francis. Daughters names known: Lucinda, Sarah, Jane, Elizabeth. Others not known." This info was from a descendent of Francis Cornwall.
