Hi Fern,
If you are still online and looking into family tree info - I have much of it figured out. Charles and Mary are my great great grandparents. The tribe Mary belonged to was White Earth Nation in central Minnesota. Charles father was George White - I think he may have come from Scotland or Ireland but I cannot find any records to confirm his origin other than he is supposedly buried in Hillside Cemetery in Portage La Prairie Manitoba. Ancestry has Mary and her children on the tribe roll and those records can be found here on ancestry with a paid membership. I pulled off copies to keep when my subscription expires. Have a list of all the children of these two with it being more complete on my direct line.
Hope all is well with you and you see this. 10 plus years... since you posted. Hope to hear back from you or any other relatives.
