Looking for Sidney Wright IN Alabama

Looking for info on my 2x great-gpa, Sidney Alexander Wright (b. Feb. 23, 1884, AL d. Mar. 31, 1942, Pittsburg, TX). He married Hannorah Russell (b. Feb. 12, 1886 d. Oct. 10, 1942 both in Camp Co. area) around 1904/1905. They had 6 children:
Florence Mae: Mar. 17, 1906–Jun. 10, 1975 (my great-gma)
Elwyn Alexander: Jul. 8, 1909–Dec. 27, 1986
B C: 1911-1922?
Harris: Jan. 8, 1913–Jul. 1987
Emma Sue: Mar. 2, 1922–Jun. 7, 2005
Hattie: 1928 (Living)
I can't find any info on him prior to 1910 census. His death cert. (info given by son, Elwyn) says his father may be named Alexander, & one birth cert. for a girl who only lived a few days lists his birthplace as "Hudson, AL" (handwriting VERY hard to decipher). I located a "Hudson Mill" in DeKalb Cty. AL, but that has turned up nothing so far.
