Thanks everyone for your suggestions. You've all been so helpful.
I followed Stan's link re Whelley [my spelling in my posting was an error, double e instead of double l] and it took me to an extract from An Archaeological and Historical Magazine Chiefly Relating to the Lancashire and Cheshire, Volume 1 published 1880 and the extract clearly states: "Whelley, commonly pronounced Whirley..."
I think the Macclesfield one is a bit far from the other Dickinson locations and Whalley House on the wrong side of town.
