This debate is interesting but I would still like to find the birth registration or even christening for my husband's ancestor Selina Fricker. She is well documented on the census records and I think her birth would be early 1850s. She was brought up by her grandparents, although some family trees record them as being parents. Her father was Mark Fricker but he didn't marry until some years later, having nipped off to the army about the time Selina was born and been discharged in Scotland , well away from Camberwell, his home. As there is no evidence of a marriage before Selina's birth, my theory is that he diappeared when he realised the girl was expecting, possibly the mother died and Selina was given to her grand parents to raise. If there was a birth registration or christening, it could be in any name you like! There is a Selina born about the right time and place but on checking, that was someone else.
