I created a tree, and noticed the following situation: a person named Maria has two siblings. Both siblings have children and grandchildren, with all the available data entered. However, these two siblings in reality are Maria's children, and a mistake was made when creating the tree by adding them as siblings rather than children. Now, what I want is to move the siblings and their families in such a way that Maria shows up as their mother. How do I do that? I really do not want to delete their family details and add them again under Maria's family.... I hope my question makes sense. Thanks!
