Yes, the census record you found shows Rachel too, parents John Braddock and Ellen (perhaps Dustan) according to online family trees.
I wouldn't put too much weight on the indigenous angle, this entry shows she was of English extraction and the term "native" was used for anyone who was born in New Brunswick. The term "Indian" was used to designate a member of the Aboriginal people at this time.
I'll scratch a little more and let you know if I find anything.
