I'm doing a family tree for English homework on Queen Elisabeth (I live in France, but I'm English). I just have to put her parents, her (plus husband) and their children. I'm getting a bit stuck on Prince Charles, what do you put for Princess Diana? How can you show they were married – is there a symbol/sign?
HOMEWORK COMPLETED :)
Thanks nottahobbit, I'll make your answer best answer when the question has expired.

Treat Diana as Charles's wife, regardless of whether she is alive or dead. She was the mother of his children, and that (the "genes") is what matters in GENEalogy.
