It would be useful if Monica could suggest adding relationships when adding family members. For example, in a family with one mother, one father and three children, once you have the parents and you add one child to one parent, it would suggest creating a parent-child relationship for the other parent. Similarly, once you have some other children in the family, it would suggest adding sibling relationships between them.
These should be only suggestions, because they would not always be true (for example, in the case of half-siblings)
