Jacob Gregg and his wife, Susanna Underwood, brought their family to Ross County, Ohio, where Jacob died in Apr 1801. My branch of the family, their son John Gregg and his wife Elizabeth Boothe, brought their family to Van Buren County, Missouri about 1840.
Another ancestor, Rev Job Cozad, and his wife Abigail Clark, also moved to Ross County, Ohio, about 1801 or earlier.
I am hoping to find marriage records for Ross County before statehood.
