Richard Porter

According to http://www.henrycort.net/gramhpor.htm -

Three other Porters – Richard, John and Gilbert – are also likely to have been Richard’s children.

Nothing further is known about Gilbert (baptised 1741). But Richard (1728) and John (1730) turn up as captain’s servants on the Captain. From 1st January 1756 they serve under Charles Catford, but John dies on 13 June. Catford also dies, on 9th September, and John Amherst becomes captain: Richard remains on board as his servant until 21 November 1759. Nothing further is known about the younger Richard’s career, but it is surely no coincidence that Rachel Porter and her daughters Ann and Elizabeth figure in Amherst’s will.
