Here's what I have on this line: About Amanda: You actually have two people combined as one, so if you can give me the source of your information on this name, it would help. Rhoda Mahala and Amanda Narcissa Elizabeth are separate people.
Rhodum "Rhody" Allen was the seventh son/first family of Nathaniel Nelson Graves (NNG) Allen and Celia Bloodworth.
(NNG was the son of John Rhodum "Rhody" Allen and Mary Emily Ransom.John Rhodum "Rhody" Allen was the son of Thomas Allen and Elizabeth McDonald(sup.) Thomas Allen was the son of Robert Allen (born in Ireland) of Charles Co., VA.
Rhody Allen was born 28 Jan 1810 in Sumner Co., TN and died before the census in 1849-50 in Marion Co., AL.
He married Elizabeth "Betsey" Spruell, and his brother Theophilus, married her sister, Sarah Spruell, probably at a double wedding in 1831/32, around New Years.
Rhody and Betsey had six children: Luke Spruell Allen, Sarah Ann Elizabeth Allen, William B.(Bloodworth?) Allen, George W. Allen, Alice/Annie Allen, Rhoda Mahala Allen, and Amanda Narcissa Elizabeth Allen.
This family moved around allot. Some of these kids were born in Marion Co., AL and some in MS.
They all moved to TX with some of the other Allens, after Rhody's death, and mother Betsey was last in Seguin, Guadalupe Co., TX, died by 1880.
Depending on who you are talking about, Rhoda married and left home by 1870. Amanda was single and living with her brother Luke in 1870.
