Sorry Toni, I think I am going to have to break your line. There is no reason to think that George King of Cold Norton, co. Essex was the son William King of Cheshire. There are no wills or baptisms to connect the two families, and Essex is on the opposite side of England from Cheshire.
Even if he were, the line would break in the very next generation. Blanche Mainwaring is said on the internet to be a daughter of Arthur Mainwaring and Margaret Mainwaring. This is wrong and I believe her ancestry is unknown. The family of Arthur Mainwaring occurs in a couple of Visitations which names his children including daughters – George, Elizabeth, Margaret and Maria (no Blanche). He also left will naming his son and heir George, a daughter Elizabeth, Elizabeth’s son Arthur Aston (again no Blanche).
