Hi,Well seeing you had no replies and considering that most King Island people come from Tas mainland there is always records.I am in no way related to your query.You will find your answer at Tas Colonial Index or portal.archives.tas.gov.au.This will give you siblings ,children etc.You can then request from Hobart Archives Original Birth certificate,Marriage etc.James Ballard i would look for a Historical Index which should be in NSW Archives.Most old records are in Sydney as well.However Marriage certificate from Launceston will give his Parents or Witnesses etc.Lewis Barlow i did not check.Best of luck should put you in right direction.Roy
