How long was the Queen’s mourning period for her beloved 1st cousin Lord Lascelles and her beloved uncle Prince John? More than a year?

About as long as it was for the Honourable Angus Ogilvy.

About this long, or maybe it was a bit longer, maybe this long?

She was not alive when john was

Prince John died well before the Queen was born, sweetie, as of course you know.

I doubt there was any official mourning period for the Earl of Harewood in 2011. His son, who was Lord (or Viscount) Lascelles before his father's death, is now the Earl of Harewood and is still very much alive, as is his own son, who is the current Lord Lascelles.

You really do seem to be scraping the bottom of the barrel for trolling material these days, dear, and you keep repeating yourself, too. It's rather sad to observe.
