93Rebecca Hill was born in Georgia circa 1832.2

On 19 November 1854 she married 92John G. Tant in Richmond County, Georgia.2 For more information about their marriage, their lives together, etc., see his profile since that information won't be repeated here.

She presumably died sometime in the 1860's, since she's missing from her husband's household in the 1870 census.3 However, I've been unable to find any source that explicitly documents her death except for a much later record that describes 92John as widowed.4

I don't know where she's buried, and indeed have been unable to find any other record of her whatsoever after the 1860 census.
