I helped a couple in the Manx Museum a couple of weeks ago re this Philip - there would appear to be no appearance prior to wedding and subsequent appearance in 1871 census after which they seem to move off Island - no Philip K. could be found in Castletown (census or births) for the period - there was the suggestion that he was illegitimate and registered as a Boyd(e) and that subsequently he was adopted by his natural father - his wife is fairly easy to trace but the marriage is not in her p-arish which is a little unusual as her family appeared to be in the adjacent parish.
