Hi Wayne, Santiago Olivares was my GGG grandfather, his daughter Annie (Agnes) married Robert Johnston in 1881 at Hawker South Australia. The Johnstons were well known horsemen, saddlers and carters who also used donkey teams to travel the Birdsville Track, and were based in Farina. I would be really interested in any other information you may be able to share. I live in Whyalla South Australia, where Robert and Annie are buried at the local cemetery. Im also more than happy to share any information I have that you may need.
