[2] Keen's Curry is distinctly popular within the Aboriginal community who are the largest consumers of the product[citation needed].
[3] Thomas Keen was born in Camberwell, south London, in 1801, but the family subsequently moved to Croydon, Surrey, and ran the 311-acre Welcomes Farm at nearby Coulsdon.
In 1825 Thomas married Harriett Toulmin, whose family lived at The Elms, 61 High Street, and the couple moved in 1831.
The search uncovered historic advertisements and even an original mustard powder tin dating back to 1904.
Joseph and Annie settled at Browns River, Kingston, south of Hobart, where they established a bakery, small manufacturing outlet and a general store.
In 1915, after both Joseph and Annie had died, the couple's sixth daughter Louisa and her husband Horace Watson took over the family's curry-powder business.
Horace was reported to be a colourful character, and daringly transformed land at the foothills of Mount Wellington, overlooking Hobart, into a large advertising sign: using heavy stones painted white, he formed the words 'Keen's Curry' in letters 15 metres high.
In a university prank in 1926, the letters briefly read 'Hell's Curse', and students altered it again in 1962 to promote a theatre production.
