Keymer baptisms are on the www.familysearch.org web site for the period 1601 to 1886 under Batch C153791 and this should cover the period that you are looking for. If you go in via http://www.archersoftware.co.uk/igi/fs-ssx.htm , you might find it easier to search the specific parish & period. However, Keymer is one of several long, thin parishes on the border of West and East Sussex that stretch away from the north facing slope of the South Downs and are less than a mile in width. In fact, it is my experience that people from Keymer and Clayton, in particular, never seem to know where they were born & baptised when they complete census documents. I have long believed that Keymer, Clayton and Hurstpierpoint form a sort of 'Bermuda Triangle' in Sussex where people seem to disappear. So, if I fail to find someone in Keymer, I immediately check those other two parishes, before looking further afield. As for the burial, Thomas had committed two sins, attempted murder and suicide, so I think that it is unlikely that he would have been given the benefit of a Christian burial in consecrated ground. However, he had to be buried somewhere and the responsibility for his burial would have rested with his parish of settlement. If that was Keymer, he might have been buried in a corner of the churchyard that was unconsecrated. Alternatively, he might have been buried in a civil cemetery and the two nearest to Keymer that were open at the time are the Extra-Mural Cemetery, Lewes Road, Brighton (opened in 1851); and the Borough Cemetery, Lewes Road, Brighton (opened 1857). Both are owned by Brighton & Hove City Council. Best wishes, Marion Woolgar Bognor Regis, West Sussex SFHG Member No: 3323
