You can get information about the Dawes Rollsat this URL: http://www.NativeAmericanHeritage.com/ht11-heritage-dawes-rolls.htmlhttp://www.NativeAmericanHeritage.com/ht11-heritage-dawes-rolls.html. I have done some Dawes Roll searches and there are many Ainsworths in both the Choctaw and the Cherokee Nations. It is very likely that your Emmie and Delvo's father was at least part Choctaw.Do you have any hint of what his name was?(What did Emmie and Delvo name their children?Many times a first or second born son was named for the grandfather?) Do you know when Emmie and Delvo were born? There were several related Ainsworth families in the area just north of Semmes, AL in the early 1800's. Do you know if Delvo was his real name or was it one of the nicknames that our Southern branch loved to use? So many of our Ainsworth men used nicknames, middle names or just initials on official documents that it confounds those of us descendants trying to trace the families.
