Because this involves Magna Carta ancestors, I am wondering if there is any proof that Ann Cox (married in 1629 to Anthony Morse) was a daughter of Ambrose Cox and Alice Heale (married 1604). Lots of online trees claim this, but as is so often the case, sources seem scarce, lacking, or unreliable.
Both the 1604 and 1629 marriages occur in Marlborough, Wiltshire, so that is a good sign. But that doesn't prove Ann is a daughter of Ambrose Cox and Alice Heale (Alice being the Magna Carta descendant). Just my luck, Ann will be a niece, and Alice Heale won't be her mother. But it would be very nice if it is true.
