Frederick Samuel Clarke was born at Wymondley, Otahuhu, on 18 August 1859, and named Frederick at the request of his aunt Mary Anne Clarke, and Samuel after his father. He was baptised at Waimate North in a private service conducted by his uncle the Reverend Edward Blomfield Clarke, who had just returned to New Zealand following his ordination in Australia.
Frederick managed Olrig, a large sheep station near Napier in Hawke's Bay, from 1894 to 1905. In 1894 he married Amy Taylor (who died in 1936); they had one daughter, Tommy.
In 1905, at the invitation of his cousin Sir Charles Elliott, then Governor of Kenya, Frederick became a pioneer cattle farmer in what was then the newly developing British East Africa colony. He farmed first in the Naivasha area and then in the M'teitei Valley on Lake Victoria, where he bred a nationally known herd of Shorthorn cattle. When East Coast fever wiped out the herd, he retired to Naivasha, where he died in 1938 and is buried at Songhor.
His daughter Tommy — Mary Clarke — grew up in Kenya, visited England before the First World War, and in 1922 married Ivan Crown Dansie, an army officer from South Africa. They raised three sons in the M'teitei Valley:
Derek (1925),
Brandon (1932),
and Richard (1932).
Tommy died in 1991 in High River, Alberta, Canada, where she had been living with her son Brandon.
The Dansie family's descendants are now in Ireland, England, Canada, and Australia.
