Martin Hunter Mauri/ce Burke

Like looking for a needle in a haystack, I am trying to locate anything in relation to this man - my great great grandfather on my father's side. He was born around 1800/1810 (it is assumed), and judging by the name, was born in Ireland, or is of Irish heritage.

He is shown on his son's (Martin Hunter Burke) marriage certificate (issued in New South Wales, Australia in 1874) as being an "Inspector of Police". Searches so far in Australia, Ireland and Canada, following up on this clue have produced no results. Martin Hunter Burke (the son) lists on his marriage certificate, his place of birth in 1834, as Vancouver Island. (presumably Canada, or as the area was then known). Again searching around this fact has also produced little usable information, particularly in relation to his father. Searches regarding his father working for the British in the area at the time, have also led to nothing, so far.

Martin's (the son) mother is shown as Cherolle/Charlotte Ricards/Richards, on his marriage certificate, and there is some possibility of tracing her lineage and that is underway, though not proving productive.

So a search in Ireland is the next step, (and maybe a last resort) looking for information directly associated to Martin Hunter Mauri/ce Burke or possible antecedents.

Any assistance would be greatly appreciated, thank you.
