Or she could be a granddaughter!! In the War of 1812, apx. 10,000 Afro-American slaves were starving because the British burned down Washington and tens of plantations! The family of Rev. Asa Senter came to Georgetown and married a lot of folks in South Carolina, and the time period for John Senter is the most accurate and possibly John is the son of
Dr. Horace Senter, son of Isaac Senter, and it could be someone from England looking for the family of cousins in America and finding them living like Indians in the French/Indian War made him aghast!

One theory. But, Dr. Horace Senter is found in a listing on
page #118 of "Marriages and Obituaries from
Early Georgia Newspapers" abstracted from the late Judge
Folks Huxford, F.A.S.G. printed by the

Southern Historical Press, Inc.%The Rev. Silas Emmett Lucas, Jr., P. O. Box 738, Easley, South Carolina 29641-0738. ISBN: 0-89308-655-X

It reads as follows:

In Savannah on 19th inst., DR. HORACE SENTER of Newport, R.I., son of the late DR. ISAAC SENTER of that place. Jan. 25. 1804."
