Hello Lynn, I have a strong feeling that the PEASE family spread from Essex into Hertford, Buckinghamshire, Berkshire, there are records online of Ps in these counties from early 1500s on. They did move into Suffolk and Norfolk. Centre for Buckinghamshire Studies has some early PEASEs. Have you looked on The National Archives and A2A? I have often wondered about the Ps in these areas but not had time to pursue them yet, however I will see what I can find out.
when I find some useful links will pass on to you.
Do you know what religion they were, or occupations?
