I finally have time to work on Alexander Gamack and am attaching notes I have on him which might be of interest to you.
Dr Alexander Gamack arrived in the colony of New South Wales from Scotland in 1830 aged 21 years. In November that year, he was appointed Colonial Surgeon of the Norfolk Island penal colony where he remained until his return to the mainland in 1836.
After a very successful career, Dr Gamack became Surgeon-General at the Port Macquarie penal settlement and following a stint in the Windsor-Parramatta area, he returned to Port Macquarie to retire and graze cattle until his death in 1888. He had two wives; Anna Cox nee Blachford (widow of William Cox who built the first road over the Blue Mountains), and Susan O’Loughlin. Anna bore him one son, John Alexander Gamack (father of Marie’s mother Kathleen), and Susan bore him three sons and two daughters.
Dr Alexander Gamack and his family were residing in Parramatta when the following article appeared in the Maitland Mercury in 1850.......
" On Tuesday morning last, during the violence of the tempest, electric fluid entered the dwelling house of Dr Gamack. The description of the circumstance by the in-mates is as follows: A ball of brilliant fire, about the size of a cricket ball entered the kitchen, where two men and a woman servant were occupied - the woman was thrown to a distance, and lost the power of speech; the men were also thrown from their places, gasping for breath. The ball of fire played and flickered under the table for a perceptible space of time, clearing the stove dust off the floor, then made its exit out of the kitchen, round to the window of the breakfast room, where the doctor and Mrs Gamack with their son, a lad of eleven years of years of age, were sitting; the fluid here exploded with an awful crack - the boy was sent from the table to a corner of the room, and Mrs Gamack was thrown violently back into her chair. The doctor received a blow on the right side of the chest; the table shook so much that one of the breakfast cups turned completely upside down; and the poor boy, who was struck speechless, when finally recovered his breath, shrieked most piteously. The family remained ill all day, especially the doctor. The postman, who was passing the house at the time, felt the shock, for his horse trembled under him. The family of Captain Chilcott, who reside near the spot, describe the shock to have been as if the house would burst asunder."
Is there anything specific you are looking for?
