Anonymous is correct; John Forbes Nash, Jr. did have two sons, named as in his question. However, as those sons are living people, even if they were added, they would be as private profiles. Further, public records for such recent events are difficult to come by, so much sourcing would come from secondary sources such as It's a Beautiful Mind, by Sylvia Nasar, which is reported to have been well researched. At this time, it seems to me pointless to make these additions to his profile. One of the mothers is deceased (she died in the same accident as John); the other is living and would also be a private profile.
