In April that year, Lady Franklin visited the new settlement at Melbourne, where she received an address signed by 63 of the leading citizens which referred to her "character for kindness, benevolence and charity".

[7] In the same year, she visited South Australia and persuaded the governor, Colonel George Gawler, to set aside some ground overlooking Spencer Gulf for a monument to Matthew Flinders.

When Franklin was recalled at the end of 1843, they went first to Melbourne by the schooner Flying Fish and then to England by way of New Zealand on board, coincidentally, the barque Rajah.

She intended the building to serve as a museum for Hobart, and left 400 acres (1.6 km2) in trust to ensure the continuance of what she hoped would become the focus of the colony's cultural aspirations.

Timeo was trained as a household servant but was deemed too "idle and disobedient" and the Franklins attempted to offload him to the Hobart Orphan School.

In 1842, Lady Jane commissioned the artist Thomas Bock to paint Mathinna's portrait in which she is portrayed famously in a scarlet dress.

Lady Jane sent the portrait to her sister in England with a letter describing Mathinna as "one of the remnant people about to disappear from the face of the earth", who has "the unconquerable nature of the savage".

In August that same year the Franklin´s were taken aback when Sir John Yardley-Wilmot arrived in Tasmania announcing that he was the new appointed governor of Van Diemens Land.

Montagu also accused him of being ruled by his wife, a claim that was believed by the Undersecretary of State for the Colonies James Stephen and Lord Stanley to recall sir John.

Accompanied by a Geological Map, Sections and Diagrams, and Figures of the Organic Remains (1845) that were highly favourable of Sir John and Lady Franklin.

Lady Franklin travelled to Out Stack in the Shetland Islands of Scotland, the northernmost of the British isles, to get as close as she could to her missing husband.

Prior accounts had suggested that, in the end, the expedition had turned to cannibalism to survive, but Lady Franklin refused to believe these stories and poured scorn on explorer John Rae, who had in fact been the first person to return with definite news of her husband's fate.

She provided moral and some financial support for multiple later expeditions that planned to seek the records, including those of William Parker Snow[16] and Charles Francis Hall[17] in the 1860s.

Finally, in 1874, she joined forces with Allen Young to purchase and fit out the former steam gunboat HMS Pandora to undertake another expedition to the region around Prince of Wales Island.

The expedition left London in June 1875 and returned in December, unsuccessful, as ice prevented her from passing west of the Franklin Strait.

At her funeral on 29 July, the pall-bearers included Captains McClintock, Collinson and Ommanney, R.N., while many other "Old Arctics" engaged in the Franklin searches were also in attendance.

Her determined efforts, in connection with which she spent a great deal of her own money to discover the fate of her husband, added much to the world's knowledge of the Arctic regions.

Lady Jane Franklin is also a pivotal figure in three novels, Wanting by Richard Flanagan (2008), The Arctic Fury by Greer Macallister (2020), and The Exiles by Christina Baker Kline (2020).
