Add 'Parent/Child' source tagging type
It would help in both discussion and or demonstrating proof (or lack there-of) of parent/child relationships, if there could be tagging that that source was proving a parent/child relationship.
This would be similar to how Birth, Baptism, Death, etc, are checkboxes/tags for sources; there would be a 'Parent/Child' checkbox.
Most of the issues that I have had in parent/child documentation have been because users make the assumptions that because the names they find are similar enough, that they believe the people involved are related, or worse, the same (resulting in a bad merge).
I acknowledge that this potentially adds to the UI (for which I love FS's simplicity), but I believe that the UI designers could come up with some way of offering to show the sources which have been tagged with Parent/Child'
The root cause really is the following: too often, I have had to spend hours manually undoing a bad merge. In the case of my Hungarian relatives, a bad merge forgivable (if not anticipated) where there are cases of 3 couples living in the same town, with both parents having same birth names, all in child-bearing years, naming their children similarly. But when parents are merged, who by some act of teleportation, have overlapping children, on different sides of the Atlantic, in the 1840's, there is a serious lack of verification of basic data.
