The Langton's by the way, are a swine to research, as Manchester has a rival financial philanthropist of the same name, and we have two branches of the family living here too, at numbers 25 and 12 ( William the banker and Charles the insurance man, probably brothers according to others, and part of the Earle dynasty of the Square, but I haven't research that tree myself properly yet so also in speculative till I prove it myself).
Damn this is a big job!
