FAQ of the moment
Q: Does the Earl of Snowdon actually have anything to do with Snowdon? Does he chair council meetings or anything like that? And what and where is Snowdon, anyway?
A: Tony Armstrong-Jones was created the first Earl of Snowdon upon his marriage to the Queen’s sister, Princess Margaret. It was a nod to his Welsh heritage – Snowdon is a mountain in Wales.
Tony didn’t have any official connection to the area, though. Professionally, he was a well-known photographer and sat in the House of Lords (link). He retired in March 2016.
Lord Snowdon passed away January 13, 2017. His son, David, is now the 2nd Earl of Snowdon.
