Among other things, he had purchased a Wimbourne House in London from the Duke of Beaufort for the vast sum of £60,000 (equivalent to £8,235,000 in 2023) and lavished further monies on that property over the period of a decade.

[3] The 11th Duke had also built extensively in Scotland, almost tripling the size of Brodick Castle and remodeling it in Bavarian style in honour of his wife.

Hamilton did inherit a significant portion of this estate, but by 1867, he was close to financial ruin when providentially, his race horse Cortolvin won the Grand National Steeplechase at Aintree.

However, his mother (who had inherited the house in London), still found it necessary or prudent to sell that property, and it was auctioned in that same year (1867).

They had one daughter: Hamilton died at Algiers on 16 May 1895, aged 50, of dropsy after several year of suffering from Bright's disease.
