Hi Stuart,
Suppose that William was Johns first male child, then is it possible that he named him after his dad ?, on the 51 census he gives his birth as Dudley, and Ann as Wrockwardine, the I.G.I. has a John nock baptised 23 June 1793, Wednesfield, parants William and Sarah, I had a poke around in the archives erlier and had a look at the Marriage that Gnu found, they were married by banns and one of the witnesses was a William Nock, there are no children born to them in the village,I searched from 1816 to 1829, which suggests they just married in Anns parish then moved on, perhaps this the other couple that is in the area?,
your John 1819, is in the archives under St. Georges,a chapalry of donnington wood, they were living in Snedshill, and he was a collier,
Best wishes
Pete
