Just to put 1761 into a historical context (thank you Wikipedia) I will just list a few events that took place in that year:-
George III married Charlotte of Mecklenburg and they were crowned King and Queen the same year.
Earthquakes occured in London.
The tune Twinkle, Twinkle, Little Star was published in France.
The Faber-Castell company was founded in Nuremberg.
The slave trade to and within Portugal is forbidden.
The British capture Pondicherry, India, from the French.
Prime Minister William Pitt the Elder fails to garner support to declare war on Spain.
All in all, it was a good excuse for a get-together, and everyone enjoyed it - and if the house could speak, I am sure it enjoyed it too. Here's to the next 250.
