there was a Jan Halfhoorn that was a commander that was captured during the battle of lowestoft 1665 @ https://threedecks.org/index.php?display_type=show_crewman&id=1... but date of birth does not tally .
Note the travel log shows he joined the VOC on 1705 ship name House in Hermet (1701) refer to https://www.vocsite.nl/schepen/detail.php?id=10427&utm_source=O...
