I decided to search Trove for newspaper articles with pictures. My surname Willison (my maiden name) isn’t very common so I did a search for Willison, then narrowed it down to South Australia and Illustrated as in the picture below.
I got 37 results from this search 21 of these were for my family. Here are some of the pictures I found.
