I don't know if anybody is still reading this thread but have stumbled across some strange coincidences.
My family name, Chambers, comes recently from Ilkeston in Derby. I know that one of my Great Grandparents is John Chambers and that there is a marriage to Mercy-Mable and possibly Martha Pilkington. John and James are family names and, although my name is Ian, my father still calls me John (it being my middle name). However, I come from a line of John and Ian Chambers with relations James and a Pilkington marriage.
My Grandfather travelled and worked in Cambridgeshire somewhere (will have to ask my Dad where and why), but I know that they were based in Derbyshire for a while and had distant links with DH Lawrence in Eastwood and the Pilkingtons (off Glass fame). However, I since learnt that the colamining industry and industrial revolution meant that there was a lot of migration around the country and various professions in the genelogy extend from baker to founrdyman.
Just thouh the coincidence was to close, that's all.
