Not automatically – and that's on purpose. When you swap one person for another, we ask about each of their family in turn: their partner, each child and each parent. Everyone can go either way. For example, if the great-uncle on your tree should really be a different man, you might say his wife and the children move across to the right man, while the wrong man's own parents stay where they are. That way a mix-up in one place never quietly drags the wrong people with it.
