Assheton was the original name of Ashton and had a family of De Assheton's associated with it including Ralphe De Assheton who's story is here, https://www.besseges-vtf.co.uk/sir-ralphe-de-assheton-black-knight/Apparently:
Curzon Ashton was formed in 1963 after the merger of two clubs, Curzon Road Methodists F.C. - with the street in question taking its designation from the First Viscount Curzon (1730-1820), whose first name, rather spookily, was Assheton! - and Ashton Amateurs F.C., who played in the Manchester Amateur Football League. The amalgamated club's name was originally Curzon Amateurs before being changed to the current name.
