Boothe Family

I am looking for any information about my grandfather, Eli R. Boothe, sometimes listed as Booth and his first wife Mary A. (Harper). Eli was born Aug 17, 1865 in Alabame but I don't know where. I have him in Jackson County on the 1900 Census, with his wife, Mary Alice (Harper), daughter age 10 - Mirtle, Daughter age 7 Marthia, and a son age 4 - Willis. I know Willis was killed in WWI in France. I can't find any information on him from the 1910 census, I do know that by 1919 he had moved to OK., and in May 1919 married my grandmother, Ida Jane Newman, then moved to Ark, Sheridan Grant Co. on the 1920 Census, I only show him my grandmother (Ida) a daughter - Daisy age 17, born in OK., and a son David age 10 born in OK.
My Mom had told me he worked for the railroad, I would appreciate any information about him, his wife or children.
Thank you in advance.
