Thanks Peter and Chris,,
Your assistance has been of great help. I actually think I may have located him through your link Peter; I've downloaded the RM of one marine who appears to meet the criteria.
I also saw an article regarding a elf tenant who captured a dhow at Pemba. Many shots were fired on both sides. I would love to get the officers report of this engagement and the list of crew on e boat. My Grandfather became a missionary in the Solomon Islands and later far nor Queensland. I have a typed up story he gave to Sunday school in far North Queensland and it provides a slightly more descriptive account of that encounter, claiming it amongst other encounters in the Solomon Islands to be the defining reason for him changing from a marine to missionary work.
Thank you both for your assistance.
