Death: Headstone.

Malen junior, married Mary Glassenbury in 1863, and had to carry his bride out of the Tabernacle because the ground outside the church was so muddy. He built a weatherboard cottage on the waterfront, later nicknamed 'The Crystal Palace' by way of joking comparison with the great exhibition building in London, and joined his brother-in-law Cain Jeliff in a fishing venture. The partnership prospered because the waters of Encounter Bay and of the two rivers were then abundant with mullet, salmon, bream, crayfish, snook and mulloway. [Victor Harbor - Page]
Malen junior and Mary Rumbelow had a large family of five sons and four daughters including: William, Malen, Godfrey, Alice, Rose (Mrs Strawbridge), Cain, Jane (Mrs Tugwell), Samuel and Grace (Mrs Buck). In the 1880s a new home 'Yeltanna' was built behind the Crystal Palace, of granite chips discarded from the granite works on West Island, where stone was being quarried for the base of Parliament House, Adelaide.

At about the same time an attempt was made to establish an oyster bed in the bay. Malen Rumbelow in 1881 offered to look after this and was paid £2/10s by the District Council. The job entailed laying two or three bags of Port Lincoln oysters in a sheltered position, and placing large bundles of wattles around them to retain the spot. Unfortunately shells began coming ashore, all with large holes in them made by some boring creature, and the experiment failed.
