I appreciate your reply, but I am left with the same questions.
The family records that I have refer to Quebec. The family member that compiled the information I referenced is now dead -- so she is difficult to obtain clarification from. I did not enter the siblings that you reference and will have to re-check my records to see if there is any reference to them. It is also possible that the wrong Stephen Tompkins is referenced -- there is a note attached by Norm Davis III that notes that.
Her marriage is noted as Ontario because of marriage records from "St. Thomas Anglican Church, Belleville, Hastings, Ontario, Canada." I presume that the church has not been moved, although I don't know how the location was referenced at that time, or in the time since the records were obtained.
I can see potential inconsistencies, and I have a lot of unanswered questions. Unfortunately I don't know French, or Iroquois, and I cannot travel to Canada at the moment. I would like to determine the correct information and more information. I have a great deal of respect for my grandmother and I would like to find more substantial information about her ancestry if possible.
FYI, my grandmother has been dead for many years now and she was orphaned at a young age by the 1918 Flu Pandemic. If you can think of any potential references, especially Native American name to Christian name cross references, I would appreciate knowing about them.
