Hacche=Hegge in OE/Hecche is used also.
I have added Hacch research to my atte Hegge research since I discovered that Haccestrete was/is Heggestrete as language progressed. The Place Name Society corroborated this in a Middlesex place name book. Edward I four volume set of patents uses Hacche and Hecche interchangeably, for the same family group, so the clerks where writing what they "heard" and the indexing was true to each entry. Aynbody out there still using Hacche/Hecche ?
