Dr. Lilian Beckwith Maxwell, a central New Brunswick historian who lived in the house, speaks of it as the cottage the distinguished Loyalist Col. Isaac Allen built in Fredericton (he also had a large estate upriver).
The heritage value of the Allen House resides in its association with the life and career of the original occupant and prominent Loyalist, Colonel Isaac Allen. This 1 1/2 storey Georgian structure dates to about 1800 and typifies early British Regime settlement. Isaac Allen, one of the first judges of His Majesty’s Supreme Court, reportedly held court in the parlour of this house. The high ceiling in this particular room suggests that it had been used as a courtroom. Allen died in 1806 but his sister Miss Hannah and his daughter Sarah lived here, the latter till her death in 1858.
This house is also significant as it was home to one of Fredericton’s leading local historians, Dr. Lillian Beckwith Maxwell.
