Heritage is a very important aspect of a being an Ulsterman.
As a half a baby Ulsterman, it is therefore vital that Jamie understands a little more about where he almost came from.
And none of his half-pure heritage would arguably have been possible without King William III, Prince of Orange.
For those of you not in the know, here's the story - complete with links - as told by Wikipedia (because I'm just back from an office party and haven't got it in me to write something original):
"King William III won the English, Scottish and Irish crowns following the Glorious Revolution, in which his uncle and father-in-law, James II, was deposed.
"A Protestant, William participated in several wars against the powerful Catholic King Louis XIV of France in coalition with Protestant and Catholic powers in Europe.
"Many Protestants heralded him as a champion of their faith.
"Largely due to that reputation, William was able to take the British crowns where many were fearful of a revival of Catholicism under James.
"William's victory over James II at the Battle of the Boyne in 1690 is commemorated by the Orange Institution in Northern Ireland to this day." Quite right too.
Jamie's new bib - given to him by cousin Katie back in Coleraine - hails King Billy's achievements. And don't argue.
(The lengths to which one has to go to contextualise / justify the use of a cute picture).
