It has been quite a few years since you posted this so I hope you get this reply. The children you listed are the half siblings of my great-great grandmother Mary Turnbull Caraway. Mary's mother was Lucy and her father was Sam Turnbull. Sam and Lucy only had the one child. However, Lucy was previously married to a John Turnbull (I guess she liked the Turnbull men) and had these 7 children with John. Attached is a snippet of he final Dawes Roll where it lists Mary Caraway and her Turnbull siblings. If you have found further information about our family I would love to see what you have!
