Baron Arklow

It was created first in 1801 as a substantive title by King George III for his son Prince Augustus Frederick.[1] Augustus Frederick was also created Duke of Sussex and Earl of Inverness, on the same day. The title became extinct upon Prince Augustus Frederick's death in 1843.

Although Prince Augustus Frederick was survived by a son and daughter by Lady Augusta Murray, their marriage (purportedly solemnized at St George's Hanover Square Church, Westminster, in 1793) had been annulled for lack of royal permission under the Royal Marriages Act 1772, rendering the children illegitimate under English law and unable to inherit titles from their father. Both children by the annulled marriage died childless, rendering the issue of their inheritance moot.

On 2 May 1831, Prince Augustus Frederick married secondly (and again in contravention of the Royal Marriages Act 1772), Lady Cecilia Gore at Great Cumberland Place, London. Not being the Prince's legitimate wife, Lady Cecilia could not be received at court. On 30 March 1840, she was given the title of Duchess of Inverness in her own right by Queen Victoria.[2]

The second creation in 1881, as a substantive title by Queen Victoria for her son Prince Leopold.[3] Leopold was also created Duke of Albany and Earl of Clarence, on the same day. Prince Leopold's son, Prince Charles Edward (who had succeeded as reigning Duke of Saxe-Coburg and Gotha in 1900), was deprived of the peerage in 1919 for bearing arms against the United Kingdom in World War I.[4]
