John Olmius, 1st Baron Waltham

John Olmius, 1st Baron Waltham (18 July 1711 – 5 October 1762), of New Hall, Boreham, Essex, was a British landowner and Whig politician who sat in the House of Commons between 1737 and 1762.

[1] Olmius remained out of Parliament for twelve years, but at the 1754 British general election he was once again returned for Colchester.

[2] Olmius had applied to Lord Bute for an English peerage in the 1761 coronation honours but was overlooked.

[2] However, in June 1762, only four months before his death, he was raised to the Peerage of Ireland as Baron Waltham, of Philipstown in the King's County.

He died in October 1762, aged 51, and was succeeded in the barony by his only son, Drigue, on whose death in 1787 the title became extinct.
