Crumps of TN

The only info I have for Crump is the following:

Evaline Crump married Joe Bishop in 1898 in Tipton County, TN and had at least 3 sons.

Eva had 2 sisters that I know of, one named Nettie Bell who married Ed Watkins

The other sister's name was Ella who married James Northcut.

They could have been born in MS or TN.
