Mrs Dennehy was born on 29 March 1934 and is a Seacliff Park resident with a lifelong connection with the City of Holdfast Bay. Mrs Dennehy volunteered in the Minda Op Shop for over 40 years, leaving an indelible legacy of service that continues to inspire others today. Mrs Dennehy was awarded the Commonwealth Centenary Medal in 2001 for her service to people with disability, and she was made an Honorary Life Member of Minda in 2016. Mrs Dennehy represents a generation of women who formed the social fabric of Seacliff Park and Holdfast Bay generally, giving their time to causes that have built a community of supporting people. Now, in her 90s, Mrs Dennehy continues to be a Seacliff Park stalwart, maintaining close connections with her community and the Council, and attending the library and church as she has done for decades past.

In 1920, Thomas and Jessie Freebairn moved to Seacombe House, having assumed residency from the original inhabitants, Edward and Emma Stephens. Thomas and Jessie Freebairn pledged to realise the vision of Emma Stephens for a new suburb by commissioning a subdivision by renowned Government Town Planner, Charles Reade. At the time, the allotments were advertised as being in the 'Riviera of the South' in recognition of the views across Gulf St Vincent. Following the subdivision, Thomas and Jessie Freebairn went on to live at Dunluce Castle, Brighton, from 1921 onward, maintaining close connections with the Seacliff Park community. Devastated by the forced demolition of Seacombe House following an earthquake, Jessie Freebairn devoted her life to serving the Seacliff Park community, including ensuring that its new residents had a church, school and other services. Both Thomas and Jessie Freebairn were laid to rest at St Jude’s Cemetery. There are no existing monuments to this family in the City of Holdfast Bay, including Streets, although the origins of Thomas Street and Jessie Streets at Seacliff Park are unknown.

Local Seacliff Park resident Glen Millar worked for Brighton Council, followed by Holdfast Bay Council for a combined thirty years. Instrumental in protecting the coastal sand dunes and establishing significant relationships with Kaurna elders that have grown in recent years. Active in the establishment of Brighton Jetty Sculptures and having a long association with and in support of the Brighton Rugby Club, Mr Millar was awarded the Order of Australia Medal in 2006 for his outstanding service to the community. Mr Millar remains an avid City of Holdfast Bay volunteer despite his current ill health.

The History Centre has recently completed an oral history with Mr Millar given his longstanding connections with both the social and administrative history of Holdfast Bay. There are no existing monuments to Mr Millar in the City of Holdfast Bay, including Streets.

Edward and Emma Stephens and their family were the first owners of historic Seacombe House, located in the suburb that is today known as Seacliff Park. They arrived in South Australia in 1838 aboard the Coromandel. At the time, Edward Stephens was the first Adelaide Manager of the South Australian Banking Company.

Emma Stephens was instrumental in establishing Seacliff Park as a community and new suburb, regularly holding events at Seacombe House and ensuring that the broader estate would one day provide housing for the burgeoning community that sought to make Seacliff Park its home. A devastating earthquake hit in Adelaide in March 1954, severely damaging Seacombe House and forcing its demolition a few years later. A remnant cottage associated with Seacombe House still stands along Mann Street, Seacliff Park today. There are no existing monuments to the Stephens family in the City of Holdfast Bay, including Streets. Emma Stephens is laid to rest at St Jude’s Cemetery, satisfied with her dream of having laid the groundwork for a beautifully located suburb with a connected community.
