I'm also looking for documentation for my 3rd GGM, Mary Ann Wheeler Westcott. Mary Ann was born in Ohio, May 1819, according to the 1900 Federal Census.
I find many online trees have Edward Wigglesworth Wheeler listed as her father. I have a cousin who has done research on this line. He says Enos is Mary Ann's Father. He says Eliphalet was Mary's brother. I'm trying to find the answer to this mystery also. I haven't attached parents to Mary Ann in my tree yet as I would like to wait until I have substantive proof. Maybe there is none.
