Not sure there is any evidence for this. Pure speculation. Just thought it was an interesting point that these people are on the same planet and within "BB-8 rolling distance" of Rey.
We all know there are no coincidences because the Force determines fate, as evidenced by prophecies fulfilled and defeating unlikely odds on a regular basis. I feel it would be clumsy for the films not to at least suggest a link, if not confirm it. I wouldn't have a hissy fit, but it would be implausible to think they would be ideal caretakers for an abandoned/hidden force sensitive child and never come across her, while so close in a galaxy so vast.
