John Hamilton, 1st Baron Hamilton of Dalzell

John Glencairn Carter Hamilton, 1st Baron Hamilton of Dalzell (16 November 1829 – 15 October 1900), He also served as a justice of the peace, and as deputy lieutenant and vice-lord lieutenant for Lanarkshire.

In 1886, Hamilton was raised to the peerage as Baron Hamilton of Dalzell. He served in William Ewart Gladstone's government as a Lord-in-waiting from 1892 to 1894.

The Hamiltons made large amounts of money in the nineteenth century, as the lands they held in Lanarkshire were sold for coal exploitation. In the late 1850s and 1860s Hamilton was able to greatly extend his home of Dalzell House, a former tower house outside Motherwell, laying out landscaped grounds at the same time.

On 29 March 1864 he married Lady Emily Leslie-Melville (died 1882), daughter of David Leslie-Melville, 8th Earl of Leven, and had issue:

Archibald John Hamilton (1868–1870) Gavin George Hamilton (1872– 1952), later 2nd baron Leslie d'Henin Hamilton (1873–1914) John David Hamilton (1878–1900)
