Is William Grey of Sandiacre, Derbyshire, the same person as William Grey of Cavendish, Suffolk?

Question

The Peerage conflates these two people, but I can see nothing in the sources for the Greys of Sandiacre to suggest any connection to the Greys of Suffolk. I am inclined to detach William's alleged son John as unproven.

I've added the Medieval tag to bring this to the attention of those project members.  I always recommend people add the Medieval tag for all pre-1500 G2G posts.

Answer 1

It's a Grey area.
