Zachariah Garrett Prince/Susan Louise DuBois Prince, Mississippi

My great great grandfather, Zachariah Garrett Prince, was born in July 1849 in Lauderdale, AL and died in 1942 in Prentiss County, MS. His wife, born Susan Louise DuBois, was born in 1854 in Franklin County, AL and died in 1940 in Prentiss County, MS. Does anyone have any information regarding the parents of either of them?
