Hello, the Snooper,
Sorry I do not have any Radnage or West Wycombe records, but I checked my others, and sorry but nothing for either Florida or Britten, including different ways to spell them.
The only nearest detail I could find were marriages in High Wycombe a Susanna Brittin in 1713, John Britton in 1764 & Sarah Britton 1771. I do not know if you records go back far enough to find any possible connection to your family?
I did also look on th BMD and found some death records for Brittens in Bucks but they was only William Britten born 1801, died in Aylesbury 1882, Jonathan Britton of Kensington, born 1793 died 1877 in Abingdon, Oxford & Sarah Britton born 1847 died 1866 Eton, Bucks.
On census I found a Charles Florida born about 1817, a chair maker born High Wycombe, but could not find him on the 1841 census to find out his family or if there was any connection to the area in or around Radnage.
So the Brittens & Floridas either emigrated, moved from the area and gave wrong place of birth, died, or possibly used another name, it does happen. Unless they moved from the area long enough before the 1841 that those born in Bucks had died.
William & Elizabeth, I also found no trace, I tried any possible mistakes in name, but nothing, so I can only assume they emigrated, changed name, gave wrong place of birth, or the most likely, both died before 1837.
Again sorry I was no help, regards Vita.
