I am looking for any info on my grandfather Robert Marion James born per SD Births 1856-1903:Name: Robert Merion James
Birth Date: 13 Oct 1893
Gender: Male
County: Minnehaha
Father's Name: Joseph Marion James
Mother's Name: Margaret Emma Lucas
File Date: 2 Feb 1942
His mother Margaret's parents were Robert Lucas and Mary Jane Mcmackin/McMakin. Margaret was born in MO, at 16 was in KS and died in Denver in 1897. Her grandparents were was Mary Jane Cook and Samuel McMackin. Robert's father Joseph was born in IL but on the 1900 census is living by himself in Boulder CO without his children and working as a bookkeeper. Robert's brother was Fred Leroy James born 8 Jul 1888 place unknown/died 1905 place unknown. Family oral history has Margaret Lucas being 1/2 NA via mother and Robert being in NA school as a youth. I am unable to find Robert's parents on any census in 1890 nor Robert & brother on any 1900 census. Robert shows up with his great Uncle Adam W James in Reno, KS in 1910 at age 17 as white. Any info on this James family or relatives in Minnehaha County would be appreciated. Thanks!
