I have other South Carolina Jett information because my cousin's father was a descendent of those Jetts, although I'm not related to them.

Peter and Mariah were the parents of James, Victoria, Harrison, and Tommie Jett.

Harrison married Luvinia (aka Viny) and they were Charlie's parents. Charlie was born in September 1892. His wife was Cindy. Their son was Charles Jett, born in 1910 who married Jessie Jackson. All of these people lived in Conway County, Arkansas. Their son is James Jett who lives in Nebraska.
