Just to update my previous message. I have now discovered the family in 1881 census. They are still in St Thomas' Oxford, but grandfather and father Matthew Dixon are not there. Matthew has died as his wife is a widow now. Rose Harriett Dixon has now married William Ward. My best wishes, Jill See website, KNIGHT, DAVIES and for 3 lines of JONES http://www.muirfamily-genealogy-online.co.uk/
