I'm not sure this will help or confuse you. From what I pieced together I have Littleton mapp, Jr married Anna Fannin and their children are: John Fielding, William F (Floyd?) and Anna Fannin Mapp. John Fielding married Elizabeth Steele and had the following children: Jane, Peninah?, John A and Lewis T? The only documented proof I have is the following Census info: 1850 MS Census (County; Hinds, Locality; Jackson, Roll No; 372, Page No; 168, Hse; 463/463) John F 55 m GA-Farmer $1000 Elizabeth 50 f GA Jane 20 f MS Peninah 19 f MS John A 17 m MS-Student Lewis 14 m MS-Student Census Dated: October 25, 1850
1860 MS Census (County; Hinds, Locality; Utica PO, Roll No; 582, Page No; 680, Hse; 1365/1383) LT Mapp 23 m MS-Farmer $6000/13390 JA Mapp 27 m MS-Not employed
I also have Lewis Mapp married Iroma Walker in OK? but I haven't connected that info to anyone yet. Would be interested in any connections you may have to add to my file. I'm still looking into the census info, but it's slow going.
