Someone very kindly sent me the inscription on the marker on the Parrys' grave. It indicates that Jane died in Nov 1876 at the age of 62. A census indicates that she was born in Dumfries. Her husband, John Parry, died in 1863 at the age of 69. He was born and died in Carnarvon, but I have no idea where he spent the years in between. Ideally, I'm hoping to track down a record of their marriage.
