Hello Ben. I am a Deed too, although married now. The Dade name - if you search for William Thomas Deed, you should find the family tree belonging to Martin Reeves (mreeves), whose mum was a Deed. If you click back through four fathers (two Williams and a John), you'll find a William Dade, b. 1749 in Hawkedon, a village near Bury St Edmunds, Suffolk. Scarily, my family moved back to Suffolk in 1973 from south Essex.
If you say 'Dade' in a Suffolk accent, it sounds like 'Deed'.
My brother - a John Deed - lives near Cambridge.
