Hi Lady Di,
I am also a Medcalf, and my home town is Enfield, and directly related to the Benjamin mentioned in your initial post - I believe my great, great great grandfather. I am a descendent through Benjamin and Benjamin Pearce Medcalf.
My parents have been visiting HALs over last few weeks, and we have a number of photos of Ware Chapel, gravestones, etc.
Would like to find out more about the Medcalfs, and maybe I can fill in some missing details, or help with the research.
