I’m not sure what tribe she may have been, But her maiden name was Emma Crow born around the 1870s. She married William Colvin a farmer in Edwards, IL. A census report at the local library said they had a worker on the farm named Crow who was Native American I think the first name was Thomas. She is my paternal great grandma. If anyone has any info or could tell me how to go about finding out more I would sincerely appreciate your help.
