Hello,
Everyone runs into road blocks in their family history. Mary Snodgrass.

*NEAL, Jesse and Mary SNODGRASS. Surety, John WILLIS. Married 22 Sep 1816 by Jerel Dodge

Don't know if Mary had been married before, so not sure if this was a maiden name.

I have found a John Snodgrass who lived in and married an Emily Isbell in Wayne County.
I am hoping there might be some connection ?? nephew, grandson?

Any help would be appreciated.
