I am currently compiling a database of Briggs's in the 1881 census (although I still have a little way to go). In all there were 16,457 individuals with the surname Briggs. For the dates you are looking at, there were 10 Richards, 59 James's & 100 Mary's - as 71 of the Mary's were wives, then no more than 29 of the Mary's were born Briggs. Just thought the information might be useful! Malcolm Briggs PS I have so far completed the Briggs who were in the 1881 census in Lancashire, so if is relevant, I might be able to provide you with more information - let me know if it is.
