Nice to make contact. I have a bit more information about Malachi Addy. Don't think he had any direct descendants but there is a little more information about his property in ourvillage history collection. It turned out not to be my house but another similar one. My email address is Stella_herbert@hotmail.com.
I will be happy to help you if you email me at that address. We are still very interested as there is an oldproperty called Northampton House in the village & it seems possible that it is the connection to him that gave the name to the house. We have a village history project in hand & are interested in anything we can find out about the past. Regards, Stella.
