Is it possible that the person who said they would do a quick “lookup” for you in a certain record didn’t really know what they were doing? Did they overlook it? Did they not consider all the spellings? Anyone can make a mistake. Might it be worth a second try?
Please don’t get me wrong, those who volunteer to do lookups do us a GREAT service, but since they are human, every once in a while they can overlook something.
