1947 on Family Tree Circles

Researching CATER Family who were born in St.George MD early 1700's then moved to Somersett, Belmont County, Ohio around 1825. So far I have two brother's John Sr. CATER and George CATER. I think their father was William CATER of MD. John Sr. CATER married Mary TARMAN 1805 in Prince George, MD. His brother George CATER married Mary D. MOORE 1815 in Prince George, MD.
If this sounds familiar with your CATER line please contact me.
Thank you, Barbara Cater
