I have just such a quitclaim between mother and son, reference 2 on [[Ianson-102|John Ianson]]. I did not know that these were more common between relatives. This is the only evidence I have for his mother's name, I am still trying to find a little more before I input her details. I have had to construct this part of the family from deeds and wills etc as they were committed dissenters and usually only entered church to marry, presumably to protect their property rights!
