I like making characters for future campaigns and have come up with a Harpy bard PC of noble birth(background). The idea I wanted to go with is that she is born in an offshoot branch of a canon noble house in the 5e lore/rule books but I am having trouble finding any. I have found some from forgotten realms but that is all. Are the forgotten realms canon to 5e, if not what are the houses?
If the information is relevant, she isn't a bastard born and is/was well cared for by her parents(harpy mother, human(?) father).
