Error
It is not evident that a child is in more than one family when looking at the family page of one of those families.
It would be helpful to see that little Johnny is not only a part of his mom's family, but that he is also a part of his dad's family when looking at members of either of those families.
I have implemented it as a test adding css including a person's ID in GroupMembers.ascx and then building the style using a stored procedure in an html block. What I have done puts the number of families the person is a part of to the top left of the person's picture. I added the number because of the potential of a child being included in more than 2 families.
This works, but would be better built into Rock itself.
