There was a serious possibility that Alfred Hamilton would provide a good match for the twelfth duke's daughter, Lady Mary, but such hopes were dashed in 1890, when Hamilton was partially paralysed by a rare tropical disease he had caught while overseas on his last tour of duty.
William Douglas-Hamilton, 12th Duke of Hamilton died on 16 May 1895 and was succeeded by Alfred as the 13th Duke of Hamilton. The 12th Duke owned extensive estates in England and Scotland; by 1883 these comprised a total of 157,386 acres which produced £73,636 in agricultural income and £67,006 in mineral rents annually. The 12th Duke's estates were valued at £1,902,559 for inheritance tax; under the terms of his will, the Easton and Arran Estates, valued at £374,713, were to pass to his daughter Lady Mary and her descendants; if she died without descendants, these estates were revert to the next Duke of Hamilton. The properties that left the Hamilton family at this time included
Brodick Castle on
Arran, which had been owned by the Hamiltons for 500 years. The remainder of the 12th Duke’s estate in Scotland, valued at £1,527,845, was settled as the
Hamilton Estates Trust which was to pass to his successors to the Dukedom of Hamilton. Despite the extensive size of Alfred's inheritance, at the time of the 12th Duke’s death his estates were heavily encumbered by debts amounting to £965,999; the bulk of these were secured on the Scottish estates, except for £117,500 charged on the late Duke’s English Estates. In 1922 the Duke disposed of 450 parcels of land comprising 19,363 acres of his estates in Scotland acres of the Hamilton Estates for approximately £330,000, most of which were purchased by the existing tenants of the estates who had been offered the right to buy their landholdings prior to auction. The 13th Duke's inheritance included
Hamilton Palace, the main
family seat. As Duke was also the hereditary keeper of the
Palace of Holyroodhouse. However, the Duke offered Hamilton Palace to the Royal Navy during the
First World War for use as a hospital. Following the end of the war it was considered necessary to demolish it due to subsidence, blamed on the family's own coal mines. Hamilton lived instead at
Dungavel House, which had previously been a Hamilton
shooting lodge on moorland close to
Strathaven. Hamilton was honorary
lieutenant-colonel of the 4th Battalion,
Highland Light Infantry. He was also honorary
colonel of the 6th Battalion, the
Cameronians (Scottish Rifles). Hamilton died shortly after his 78th birthday, on 16 March 1940 at the family's property in
Dorset,
Ferne House. ==Family==
