Debbie, After looking over our GA ALFORD census data, I think I agree with your grandmother. Have you checked Washington Co. GA marriages? If her first child was born 1907, I would look at 1905 and 1906 marriages. We do not have a Mamie/Mammie on our GA marriage list as yet but I am sure we do not have even half of the pre-1900 marriages much less those that occurred more recently. Do you have a date and place of the marriage to George Lindsey?If the children were officially adopted by George, wouldn't there be papers giving their legal names?If they were not ALFORDS, then the surname they had was that of their father, i.e., Mammie's first husband. In checking the 1910 census for a Louise and a Bonnonie, the closest ALFORD household that matches was that of a Benjamin C. in Hart Co. which is far removed from Washington.They also had a son Elmer, born 1904 and the wife's name was SUMPTER, not Mammie. There is a Mammie A. Alford, dau. of Eliza and Thomas Alford (who was deceased) who is listed as being 14 (born 1886) in Washington Co. GA in the 1900 census.There is a Mamie Alford, age 18 (born 1892) in the 1910 Washington Co. GA census, who was the daughter of a James and Sallie Alford.I think the one you are looking for is the Mammie present in 1900.If you can check with Washington Co. for a marriage date and spouse's name (or determine spouse's name some other way), maybe we can help you further with her background. Did she die in childbirth?Did the children George adopted change their names to Lindsey?Where did you get the birth date of Mammie and the other information you have on her movement?Where would she have been in 1910? I hope to be able to offer more help, but I think we need to find that first marriage which we don't have at this time.
