Unmerged matchs survive almost anything. They should be merged, just as the primary profile was. Notice Brewster-81, he is listed as the father of two Wrestling Brewsters. They need merged, but haven't yet been. Notice, too, the number of people who have contributed (managers) to this profile. No one 'owns' the profile, but all have contributed and all of their contributions (except these Wrestlings) have been merged together.
The lowest numerical profile is the one that survives. It may be improved by the merge, gain information, but the lowest number is goal for each merge, by definition.
Feb 2013, these extra children have been merged. THB
