I know very little about the Rotherham Ridg(e)ways apart from what is available in the 1881 Census I have. I am trying to expand this by correspondence recently with Peter Ridgway who descends from this group of Ridgways; I hope to hear from him shortly. My Ridg(e)ways in the main came from the North Buckinghamshire area and are well-documented there and the earliest of the Lydia's I have on record dates from about the mid-1820's - sorry.
