What dose this mean regarding the British Royal Family Tree?
We know what a cousin is. “Times removed” means generation differences. Let’s take an example. My “Auntie Betty” isn’t in fact my aunt but mum’s cousin (one of many – her mother had 12 brothers and sisters! Mum is the daughter of the 3rd child of that family, while Betty is one of the children of the 1st child of that family, so they are 1st cousins) but I always knew her as Auntie Betty when I was young and we used to visit her a lot. I am Betty’s 1st cousin once removed because I am of the next generation. Betty’s 2 daughters are my 2nd cousins because we are of the same generation but are all children of 1st cousins. Their children are my 2nd cousins once removed. How it goes with the two Queen Elizabeths is that their closest common ancestor is Henry VII. The nearest relative when Elizabeth I died was King James VI of Scotland, who thus became King James I of England, and Elizabeth II is descended from him. One of James’s great-grandmothers was Margaret Tudor, sister of Henry VIII.
