I was born and brought up for a few years in Audenshaw. Ashton has changed, but some parts are still reconisable - the market hall and market place are still there and busy. You could go to the Council's website
www.tameside.gov.uk if you haven't already done that. Sorry that I can't help with your search for relatives. Have you tried some of the on-line family trees? Or a web search for any family names that you remember? Just looked up your surname in the phone book for around that area, 2 names but without the e on the end of the name. Good luck in your search.
