Initially concentrating on Faulders born in Cumberland (and their descendents) as detailed by the censuses of 1841-1911. This work is being held on Ancestry.co.uk. There would appear to be about five strands of Faulders in Cumberland. By charting them it is possible by matching some people to unrelated strands to be certain that they are not part of our strand. Unless, of course, tracing their ancestors gives a clue to ours!
