From Re: Josiah (Josias) Churchill (ca. 1613 - 1686)
The younger son, William of Dorset, whose wife as you say was Mary Creuse, was born between 1490 and 1495 and died before 11 July 1583 in Piddlehinton, Dorset.As you say, he had sons John, William, and Roger, though he also had a fourth son, Alexander.The Marlborough line is, as you say, descended from Roger.
