The Wedges imported sheep and a saw mill into the Van Diemen's Land colony.
Mr Wedge obtained a 2,000 acre (8 km²) grant, which he called Forton, but at first he tried to establish the saw mill at Oyster Cove, just south of Hobart Town.
He then turned to agricultural pursuits, and established Forton with the assistance of convict labour.
After the settlement of Port Phillip in 1835, he and his brother John established a squatters run at Werribee, near Melbourne, and in the 1840s Davy and his wife left Forton for the Werribee run.
Davy, his wife and daughter Lucy were all buried at the Williamstown Cemetery.
