Just for general information- how about the following construct-
Gilbert is the son of William Clement and Elizabeth Burn ( Bourne) married 1771. Elizabeth's father was Gilbert Bourne and her mother was Mary The children of William and Elizabeth were Mary, 1775, William 1777, James 1780, Elizabeth 1782 and Gilbert 1785. The naming pattern is obvious, leaving out only James. The IGI shows only 2 William Clement births in Durham between 1714-1754 ( aam 17-57), one of which was 1729 (aam 42) with father James. I haven't proved it - would need a death date for William as a starter- assume dead at 70 =1799, but it fits nicely, as all such constructs do until blown out of the water by facts
