BELVILLE is not a name that is found often in Sussex, but there are some entries for that surname in the registers of Broadwater, St. Mary. You have obviously made a number of searches trying to find Louisa BELVILLE born circa 1837 Worthing and others who have attempted to answer your query have obviously found it equally difficult to find any trace of her prior to her marriage in 1857. Now, this is a *very* long shot, but as she appears to have been born illegitimately according to her Marriage Register entry, I am wondering whether Louisa is her birth name, or one that she chose for herself later in life, or perhaps it was changed for her by an institution or by an employer. This was not uncommon. Barrie Keech has transcribed the registers of Broadwater St. Mary and you will find the details on his web site at http://www.barriesgenealogy.co.uk/html/st_mary_s_baptisms_1558-1909.html . On 31 Jul 1836, there is a baptism for an Ellen Sarah BELVILLE, daughter of Elizabeth, a spinster of Worthing. This fits the surname, date, place and circumstances of birth it is only the Christian names that are different. On the 1841 Census at HO107/1095/3 folio 41b at Broadwater Street, an Ellen BELVELL aged 4 is living with a James & Charlotte MUNNERY. Could this be the child who was baptised in 1836? Is she any relation of theirs, or could she be a child that they are fostering from the workhouse? It might be worthwhile to try and find Ellen Sarah BELVELL or BELVILLE on the 1851 and later census returns and see what happened to her. If you find her, then the whole idea is a non-starter; but If she disappears off the radar and cannot be accounted for by a death or burial between 1841 and 1857, then I would be tempted to take a look at Elizabeth BELVILLE and see if she can be fitted-in to the BELVILLE families living in Worthing in 1841 and see where that leads. At the very least, you will have eliminated another possibility and you might just get *very* lucky! Best wishes, Marion Woolgar Bognor Regis, West Sussex SFHG Member No: 3323
