As regards the matter of the two Dixons, I think the 1891 census (in which my grandfather and his brother feature) might fill one or two gaps. The name of the house is given simply as Park Villa. The profession of Thomas Dixon (head of the household and aged 51) is given as School Master and his place of birth as Stockport, Lancashire. The son, Geoffrey, aged 23 is described as a Medical Student.
