Im newer to this line so Im still working away.
I had known my grandfathers biological mother was born Gladys Rolfe, and had a brother Walter Rolfe...but both had been adopted out to different families. Her to the Randell family, him to the Rice family.
I have no idea on any native history, but would be interested to find out. Im still working on finding out why the children were adopted out, if both parents had passed away or for another reason.
If you find any new information on these lines I would love to hear about it :)
