Hi Claire,
I'm not surprised that Gefferie had an A in his name, that was how they began. It only seems to become Denchfield after Gefferie, Richarde and the Baptism entry for Matthie, son of Richarde mar 7 1600/01
I haven't any Denchfield wills yet, I've been a bit busy with another branch of the family.
Now I know about it, I think Gefferie's is a must.
All the best
Paula
