Hi Tammy,
My name is Dawn, I'm Paula_Fish1's daughter. My grandfather, Maurice, was Roland's brother. I know you posted this information quite some time ago and I was wondering if you found out anything. I know the rumour was blackfoot, but given the region and the fact blackfoot are traditionally in the Calgary area, i think the ancestry is more likely Mohawk. If you're still active, which I'm not sure if you are, you can also see my part of the family tree. Quite a few people were related to the original 15 and they have managed to trace some of the family line back into the 1000's, an impressive feat.
Thanks.
