BOURNE, Loader (Grimwade p.284)

[silverly]

24 April 1715 Loader son of James Bourn in Union Street shipwright.baptized at Saint Nicholas, Deptford.

27 October 1727 Loader Bourn son of Mary baptized at Saint Thomas, Portsmouth, Hampshire.

18 June 1729 Michael Lade of City Canterbury goldsmith paid apprentice indenture duty for Loader son of James Bourn of Shurness.

27 May 1762 William Tringham London goldsmith paid apprentice indenture duty for Loader Bourn.

29 May 1798 Loader Bourn married to Eleanor Jones at Saint Martin in the Fields Westminster.

This does not quite look like a father and son match up to me, but it does appear that there were two Loader Bourn's in the same trade.
