Hello from Adelaide, South Australia. My mother's maiden name was Abernethy. Her father was William Abernethy who lived at a small outback town in South Australia called Tarcoola. He was a mail coach driver in the 19th Century, delivering mail and supplies between Tarcoola and Port Augusta. His wife's name was Rebecca but do not know her maiden name or anything else about either of them. My mother's name was Hazel Alice Abernethy. Is this of any use to anyone? At least get your atlases out and have a look at where this all took place!!
