In the early part of the voyage the prisoners suffered mostly minor ailments, however many had been used to a diet that consisted of mainly potato and from the sudden change on board ship and in conjunction with sea sickness, many suffered from obstinate
constipation. By mid July, three months into the journey, sixteen of the men were affected by scurvy.

complexion was dark, ruddy and pockpitted. He had dark brown hair, and dark grey eyes.
Peter was granted a Ticket of Leave, 14th Feb, 1846. He didn't muck around, as he then married Mary Pearson in

In the story about the "Lockyer" murder, there was a Miss Gallagher who helped Martha Lockyer after she was stabbed in April 1886. It's possible this might have been Mary or one
of their daughters. Their house would have only been 5 or 6 kilometres away, over the next valley.
Mary died in Armidale in 1888.
