With the help of a fellow Rootswebber (thanks again Sheila

) I finally have a baptism date in July 1838 for one of my ancestors but have been unable to find the registration of his birth. The censuses all give his birth year as c1839 which fits with the baptism being of a baby and not an older child.
Some confusion had arisen over the fact his mother was married to someone else at the time of his birth, she was widowed 3 years later and remarried to my ancestors father. On all the censuses he carries the name of his natural father which was his middle name at his baptism.
I've searched and searched for his registration in the name of his natural father and the name at his baptism with as many variations on spelling as I can come up with and found nothing.
Is it possible the birth was never registered? Was this a common occurence especially if there was some scandal surrounding the birth? Or is it more likely that the registrar may have mis-spelt the name totally?
Also I'm wondering about how a person can be baptised with one surname and then using another name for the rest of his life. Would the names have to be changed 'officially' on his mother's remarriage or did people not bother too much with that sort of thing back then?
So many questions.....
