In researching the Conyers family (my ancestor Dennis Conyers came to Virginia in the 1710s), I found the will of Samuel Conyers, citizen and plasterer of London, dated 22 Feb. 1716, proved in the Prerogative Court of Canterbury, 12 Mar. 1716 (this would be 1716/7).In it, he gives to his daughter Martha Izard, the wife of Michael Izard of "Pensilvena."His other child was his daughter Elizabeth Sausun, wife of John Sausun of St. Johns at Wapping, Middlesex, cooper.He also asks to be buried "amongst the people called Quakers."
Samuel Conyers, son of Joshua Conyers, of Braybrooke, Northamptonshire, gentleman, was apprenticed in the Plasterers' Company in 1658 (I don't have further details at hand).Joshua was a member of the family of Conyers of Wakerly, which appears in the published Visitation of Northamptonshire, 1681.This family must be related to the ancient Conyers family of Durham.
You should look in the Quaker records at the Friends Historical Society in London to find Michael Izard's marriage record, which would name his parents and their residence.
