He was educated as fellow commoner at Jesus College, Oxford, before making the Grand Tour with the Marquess of Buckingham;[3] he gave a copy of Guido Reni's St Michael subduing the Devil, acquired in Rome, to Jesus College chapel.

In May 1784 he was created an English peer, Baron Bulkeley, of Beaumaris and had to vacate his seat in the House of Commons.

[3] Lord Bulkeley bought Beaumaris Castle from the Crown in 1807 for £735, incorporating it into the park that surrounded his local residence, Baron Hill.

His estate was inherited by his nephew, Sir Richard Williams, 10th Baronet (the son of his half-brother), who assumed the additional surname of Bulkeley, by Royal licence.

[11] His wife died in 1832; her will left property to a relation George Fleming Leicester, under the condition he change his surname to Warren.
