 The first land grant in this area was for a farm in 1794 , to former convict and jailor Henry Kable . The land in the eastern corner of Summer Hill was an additional grant of 30 acres ( 12 ha ) made to Henry Kable in 1804 . This eastern corner would subsequently become part of the estate of James Underwood . Underwood died in 1844 and left a will so complicated that it required special legislation before it could be subdivided .
