If a date or anything else is changed!on a profile, the source for that information, such as a possible baptism Certificate, should be added to the profile. Looking at the changes log for that profile, there was an Ancestry tree that was included, but that was removed from the profile. Although family trees are not good sources, it is possible that there is information attached to that tree that may have information, so nothing should be removed from profiles, especially since that profile has limited sources.
