It is very difficult to sort out families at these early dates without personally searching through a number of wills films and parish registers on film, where it is much easier to see family groups and identifying details. If you also look at other wills in the same parish as you go through the films you often find ones for siblings and other relatives, and these unexpected finds are often the ones which build the whole descent.
If you look at the Joughin message I posted yesterday you can see how much I depended on wills and parish registers to establish which Andreas family was which - rather than merging them together as others had done.
