I have now got a bit further with a tentative family tree, all in West Tarring from IGI
Edward Weston m Agnes (I can't find his birth, their marriage, her surname, their deaths).
They had son
Thomas Weston(b around 1558) mar Elizabeth Whyte (poss marr 1584 Chichester or 1585 Tarring, can't find deaths)
They had son
Richard Weston, chr 15.9.1595 mar Alice (can't find their marriage, deaths or her surname)
They had son
William Weston, chr 19.7.1634 d 1706 mar Hesther.
and after that I am OK.
If anyone can expand or confirm this I would be delighted!
Ann
