The township of Marion was laid out by William Light and B. T. Finniss in 1838, and was named for Marianne Fisher, daughter of the Resident Commissioner, James Hurtle Fisher. Vegetables, stone fruits, almonds and grapes were all produced in Marion. Richard Hamilton started the first vineyard in 1838 and his family continues its wine making tradition to this day. By the late 19th century Marion was also home to a number of industries such as a mining and brick making. However, the population at this time was still very small – around 350 people. Gradually the Adelaide sprawl crept up to Marion, and by the 1950s the suburb was well and truly enveloped.
