[10] The office of Ulster King of Arms, Principal Herald of Ireland, was created 1552 by Edward VI, with full jurisdiction over Irish heraldry.
However, from the start of the eighteenth century Ulster began to acquire other duties, as an officer of the crown intimately linked to the government.
An additional responsibility came in 1783, when Ulster King of Arms became registrar for the newly established chivalric Order of St Patrick.
Wilkinson was appointed Ulster King of Arms in 1908, succeeding the disgraced previous office-holder Sir Arthur Vicars after the theft of the St Patrick regalia in 1907.
Major Wilkinson apparently spent most of his time in London at the Office of the Keeper of Royal Arms.
By 1923, Wilkinson had begun visiting the office regularly, which caused a minor political problem for the fledgling Irish Government for sixteen years.
Wilkinson was appointed Commander of the Royal Victorian Order (CVO) after the visit of King George V to Dublin in 1911, knighted in the 1920 New Year Honours,[11] and appointed Knight Commander of the Royal Victorian Order (KCVO) after the state opening of the Parliament of Northern Ireland in June 1921.
The couple moved into Mount Merrion House, in the south of County Dublin, Ireland, where they lived until the start of the First World War in 1914.
Titania's Palace remained in the family for many years, but was sold after 1960 first to an English amusement park, then to Legoland and is currently lent to Egeskov Castle.
