Hi Rho Yes, I did know, that Grindon Hall was now a school, I was fortunate enough to be invited back there, when the school, had finished having the alterations done. I'm pleased to say, they kept quite a few of the original features, which was nice to see. Obviously some things had to change to accommodate, the children. It still remains a magnificent building.
Regarding the family tree, the information I have was obtained from Sunderland library, due to the records being quite old, and hand written some of the text was barely visable.
I have the children of Sir William and Hannah, and whom they married, it is from there that I have blanks, although the sons children are clearly recorded, the daughters, were scribbled all together on one page, which was difficult to read.
You probably think I'm nosey, wanting to know about the family tree, but with researching the history of the building, and finding out how Sir William was such a prominant figure in the area, I became hooked.
Having researched my own family and only getting back as far as 1816. It has been interesting looking at the records of your family. Regards June
