Wisdom Farm was a house and tenement, situated on the eastern side of Polled Oak Slade. In the Tithe Award the 'house and garden' was measured as 3 roods and 12 perches; described on the OS Map as 0.784 acres.

In the first half of the 18th century, Wisdom Farm was held, copyhold, by Thomas Sweatman. In 1738, Thomas Sweatman sold the land to Arthur Harding.

Arthur Harding held Wisdom Farm until his death in 1786, when it passed to his son, also Arthur.

Arthur junior, died in 1833 (recorded in the court rolls as Arthur Harden). In his will he left the Farm to his daughter Harriet Honnor for her life and then to her four children. Harriett died in 1858 and her only surviving child was Harden Honnor a farmer of Laleham in Middlesex; Wisdom Farm passed into his hands.

From about 1855 until his death in 1892, Wisdom farm was rented and farmed by David Cook.
