Just saw your post Mathew. It would in interesting if any of your ancestors were of Haddenham. There were Burkitt's in Cottenham but not sure how related. I know their is indication of some Burkitt names in Haddenham in about 1900. For example: In the 1900's on Hop Row street in Haddenham ..
Steel, windmill maker/electrical shop/antiques: Poole, general stores: Wright the barber/ladies hairdresser: Burkitt, cycle repairer: Burkitt, threshing tackle works/ Mclarens Garage/Manchetts Garage.
Wood sales were held in the Three Kings Yard: Peter Steel, nurseryman, Hovell, saddler.
