My Brick Wall Israel Phillips Martha Tillman of TN MS

I have a marriage certificate for Israel Phillips and Martha Tillman, Aug 28, 1810, in Williamson, TN.
They moved to Mississippi and had three children:
1. Hayden Tillman Phillips (1820-1900) Marr: Caroline Russell
2. Amanda Phillips (1821-1870)
3. Rebecca Phillips (1822-1850)

Owned land in Mississippi in Copiah County.

That is all I can find on them online. They are my 4th Great Grand-Parents of which I am a direct descendant.

Any help would be greatly appreciated.

Randy Phillips
