Hello Rod
I have recently been doing some research into the early brethren in Hereford, and George McAdam is amongst names mentioned.
I have confirmed that Theresa is buried in the graveyard in the same grave as Harriet Eccles her mother, but I dont think it mentions George, but one would assume that he is also buried in this graveyard.
If you would like me to confirm this for you, I am happy to go and have a look myself, I would need to get permission from the owners of the Hall as you cant access the graveyard without going through the hall.
I would be very interested to hear what you have managed to find out about your GG grandparents, and also I am trying to trace another descendent of Henry & Catherine Young nee Eccles who I am told is a Elizabeth Wilson from Sydney - if you know anything about this, I would be very interested.
Many thanks
Phil Smith
