Interesting that the death certificate of the *second* wife lists children that the profile page associates with the *first* wife. Yet they are clearly not the second wife's children if a) she was married only 25 years, and b) the children are older than 25 years of age.
In fact, it would appear that the second wife (the deceased of the death certificate) had no children-- unless they're the dead ones-- as there is no child listed on her death certificate younger than 25 years.
