 Pemberton Grange was conveyed in January 1838 to Captain John West, with the 18th Regiment of Foot, then stationed at Windsor, by way of a mortgage secured from West and repayable to Palmer in 1840.This arrangement suited both parties until 1851, when Captain West, then in England, and Palmer, having returned to New South Wales, having been staying at his station Ginninderra (near present-day Canberra and developed by Palmer from about 1826) since at least the mid-1840s, agreed to convey Pemberton Grange and the 90 acres to merchants Robert Campbell and John Campbell in trust.Palmer was related by marriage to the Campbell family in numerous ways.
