I am researching Mary Gunning who was sentenced to 7 years transportation to New South Wales in October 1833. Mary was from Galway, Ireland, and at the time of her trial, she was married to Daniel Gratidge (his surname could well be incorrectly spelled) who was, supposedly, a soldier in the 17th Regiment Mounted Police. I cannot find any reference to this regiment, only to the 17th foot regiment from Leicestershire who were sent to Australia in the early 1830s. There is no indication that Mary and Daniel met up in New South Wales and I can't find anyone with the surname Gratidge or numerous variations using Ancestry. Any help will be most gratefully received.
