Thanks for your help on this. I'll order a few of the birth certificates and see if I can find out anything. I'll let you know if I do.
One thing that I did notice was that on the marriage certificate of Henry Gilbert Lovell and Mary Eva her address in 1875 is given as 1 James Street Newport. At the 1971 census there is a Thomas Evans living at that address. I did try and trace him back but could not find any sign of a Mary Jane living with his family in 1861. I think its just a co-incidence and Evans is such a common Welsh name.
Bye for now and thanks so much. Sue
