Hi maidmarion
From the 1861 census there was a Margaret Jones, 1 ,listed as dau. of Mary(Margaret?) Jones, housekeeper and , possibly, John Edwards. I noted that the housekeeper was listed as married. Was she married to a Unknown Jones, the father of her child? I found a marriage of a Thomas Jones to a Margaret Owens in Wrexham in 1857. If this was correct, they could have had a child, Margaret in 1859/60, separated, Margaret destitute goes to work as housekeeper for John Edwards which takes us to 1861. Possible !!
