What follows is entirely the work of my maternal cousin, Roy William Shakespeare, who is the genealogical head of the family and who has been a family historian far, far longer than I. My direct ancestors are shown in red.
I am descended from Joseph Shakepeare's first wife:
Places of birth or baptism were: Ipsley, Worcestershire (1651 - 1665); Studley, Warwickshire (1696 - 1733); Preston Bagot, Warwickshire (1757 - 1761); Henley-in-Arden, Warwickshire (1777 - 1829); Birmingham (1840 onwards).
My maternal grandmother's family - Spargo of Gwennap, Cornwall - is worth a look.
