hi Skewbald
I noted your comment, about Thomas Chambers, where on p72 in my first book 'Rhosneigr Then and Now' I have written "In 1857 one Thomas Chambers, a pauper, is recorded as living at Tyddyn Leci in the parish of Llanfaelog."
This research was carried out during 1988 and 1989 - way before ancestry.co.uk, the internet and google - and all of my research was carried out either in Libraries, or by interviews with a lot of 'old people'.
According to what remains of my records, which I have to confess are now pretty much broken up and now so very sketchy (and my original typed documents with references were on a very old word processor that is now defuct) it seems that the information probably came from the land Tax records (which would have been stored at the Archives in llangefni).
I have had a quick look through the early voters and land tax records in my posession, and can only see Chambers in 1819 and 1924 (not in any of the part-complete 1832 or 1885 lists I have).
1819 (land tax record) - at Pant y Brandy are Richard Chambers, Mary C, Ritchard C and Owen C.
1832,1889,1919, voters lists, none spotted
1924 (voters) Emma Chambers at 'Sandona'.
1929 none
1934 none
I'm afraid after all this time, that's the best answer I can give you.
