My gg grandfather was James Robert "Jim" Creamer, born April, 1847 in Alabama, d. 1923 in Texarkana, AR; married to Mary S. Jobe (b. 1853, Itawamba Co., MS, d. 1925, Texarkana; dtr of Jeremiah Jobe.) My James Robert had a sister named Elizabeth Jane Creamer, who my information shows was born in July, 1858, in Magnolia, AR. (According to my info, there was another brother born in January, 1860, which, if it's correct, would pretty much rule out a July, 1859 birth date for Elizabeth.)
The genealogy information I have otherwise fits with yours, except that I show their parents to have been a previous Hugh Smith Creamer (b. Oct., 1819 in GA, d. abt 1875 in Hopkins Co., TX) and Elizabeth Jane McKinley (b. abt.1825, GA - d.1871, Hopkins Co., TX.)
Around 1848, the family moved from Alabama to Magnolia, Columbia Co.,Arkansas, where the later children were born.
I may be speaking out of turn, but the information I have shows that Waymon Creamer(whose message you were replying to) is descended from Calvin Lafayette Creamer, brother of James Robert and Elizabeth Jane. They appear to have had several other siblings, including the Hugh Smith Creamer who was born in 1856 in AR and a brother named William Thomas Creamer, born in 1844 in AL. Unfortunately,I don't have any information about the siblings' descendants. This was a very prolific family, so there may be many! There are a lot of Creamers in Texas.
James Robert Creamer was blind in one eye. The family story has it that this was the result of an unfortunate childhood pea-shooting incident involving his brother Calvin.
