Just a footnote to this, Kateinperth, the Cambridgeshire Archives moved from Shire Hall, Cambridge to The Dock, Ely in late November 2019, and only seems to be open now on Tuesdays, Wednesdays and Thursdays. Sadly gone are the days when I could walk the couple of miles across town and up Castle Hill and visit the old location and do a few lookups for fellow Rootschatters...
