My great grandmother was a Summerskill from Colne in Lancashire. In the main, her Summerskill ancestors came from the villages of and around Hetton and Cracoe on the Yorks/Lancs border. Several generations were 'carpenters' and I believe - although I must take some time to look at my records - that some of the family (not my direct line) moved to Manchester. Let's not get too optimistic but a connection looks to be a possibility! I will check on my data and write again.
