I found some information in the 1900, 1910 and 1920 census. Your family lived in Lanette during all three census.
According to theses census, Rena's husband was Joe James. He was born around 1857 in Alabama. In the 1910 census, they listed the years they had been married as 17. (1893). But in the 1900 census, it states they had been married 10 years, (1890). Rena's age is also way off in the 1900 census, they had her being born in Dec 1857. I think this was the census' taker's fault in Chambers County, because they did the same to my gg grandmother who lived in the same county.
I found the following children in some or all the 1900, 1910, and 1920 census:
(1.) Joseph Jr. - born 1897
(2.) Shirley (?), spelled Shiay born 1899 - she isn't listed in the 1920 census. born - 1899.
(3.) William - born 1903
(4.) Henry - born 1904
(5.) James (Jim?) James -born 1909
(6.) Mary - born 1913
(7.) Susan Jane - born 1902. Strange because she wasn't listed in the 1910 census, only the 1920 census. She was listed as the daughter of Joe and Rena James.
(8.) Sugar R. James - born May 1899. She is only listed in the 1900 census, but I believe Sugar and Shirley were the same person. She isn't listed in the 1920 census.
I couldn't find a marriage listing for Joe and Rena to give you Rena's maiden name. I did find a death record for a Rena(Jonas) James. This Rena died Jan 1929 in Talladega County.
Anyway, I hope this helps you in your search. Good luck.
