John Hamilton Gray (June 14, 1811 – August 13, 1887) was Premier of Prince Edward Island from 1863 – 1865 and one of the Fathers of Confederation.

Gray was Premier of Prince Edward Island from 1863 to 1865 and during that time he attempted to alleviate the problems of the tenants by passing the fifteen-year purchase act, but the final solution of this question had to await Confederation.

The name of the estate is in reference to the Battle of Inkerman where his father-in-law Sir John Pennyfeather, had lost honours to an older man.

Inkerman Drive which once led to the house, is lined with trees planted by Gray and replacements of the same species, to represent the sides in the Battle.

Linden on one side (Russian) and a mixture of white birch, beech, mountain ash and poplar on the other (French and English).
