This image was constructed using Wikipedia's family tree templates (sourcecode below). I'm not good with images, so it would be great if someone could edit the colours so that they look good on the wiki. Also, I don't really know where it should go. Dotted lines indicate intervening generations that we do not yet know about. The order (left to right) of children does NOT indicate the order of their birth, in general.
A second, condensed family tree, with only canon characters included.
