My interest is with respect to my g-g-g grandfather's connection to John. My g-g-g grandfather, Thomas, was a dairy farmer and was from Green Lanes. It seems pretty obvious to me that they were related in some fashion given name, location and occupation.
I am trying to find out the exact connection.
If John Tonks is your ancestor then we have some sort of family connection albeit distant one.
In addition I have a transcription of a lease John entered into for a farm known as the "Custard House Farm" (BTW there is a pub known as the "Custard House" that sits on the former farm.) I will be quite happy to forward you a copy of that lease.
