I am searching for parents of Simeon R. McCoy and Elizabeth McCoy McVay.
The siblings are on the 1850 Dallas County, Missouri, census.
They were both born in Jackson County, Alabama.
He was born around 1834 and she was born about 1827.
We are guessing their father might be Joseph McCoy, but have no way to substantiate.
If you have any other info, please share.
