Sorry this is going to be so vague, but I'm trying to find info on a family of Quakers from York. They were Thomas Harrison and his wife Elizabeth Denison, and the only date I have is the birth of their son Peter in 1716. I know what happened to their sons, but nothing about Thomas and Elizabeth. I've tried every Quaker info site, and the Borthwick Institute is closed, so I'd be grateful for any baptismal or other look-ups.
