Bruce - Please get in touch! I'm a distant cousin of John Adrain Ardis and also have information on the family, with discrepancies! First that John Adrain drowned in the Riviere Desert on the date you have. Second that Bridget Groulx was born in 1859 and married him in 1885, which fits with the births of their 3 sons. The widow Bridget married again and I met her daughter Annie Grant in Quebec many years ago.
My branch spells the name Ardies.
