the newspapers require a subscription but available from www.imuseum.im - might be worth a short sub but they are only 1 line entries - the burial for Thomas corresponds to an entry in Brian Lawsons bur reg index but he has age 15 rather than the 57 in paper - I might check tomorrow in Museum but there was only 1 burial as a list of names of those buried was also included in papers presented at convocations where presentments landed up and I photo'd all these! but they give no other info than name whereas the burial reg should have more - there might be a MI as buried in Braddan old yard
