Bowerman named his estate 'MARION' developing an orchard and vineyard on the land, and he built the "MARION" homestead on the hill where present-day Rydalmere East Public School with sweeping views of Parramatta River now stands. Mrs Bowerman put the estate up for sale in 1857, though it was 1862 before she actually disposed of it at auction. Jamed Hartwell Williams, a well known colonist and long time American Consul resided at 'Marion' for several years in the early 1870s. The estate passed into the hands of developers in the 1880s who renamed it the 'Broadoaks Estate' and 'Broadoaks House'.
