And I have pix of William 1790's grandson William Wilce Pewtner and his family.

So, Pauline, Angela and I all have connections (mine not a descent but another branch of my Pewtner family) to William 1790 and I believe we have reached a consensus that his ancestry goes -
William Wilce 1790 and Mary Whittingham
John 1757 and Elizabeth Blakeway
John 1726 and Sarah Rudge
John 1702/3 and Anne Evans (thanks for pointing out the bap Pauline)
John 1678 and Mary Tailor
John 1640 and Katherine

Not being a Wilce completist, I'm happy with this and will leave the other line with Thomas Wilce, and Elizabeth Meek marriage in it to others.

Thanks to all for your contributions
