Yep, you were close - but I was just thinking about how mothers are so often very picky about people spelling their children's names right! Like my friend Justina - if you accidentally leave off the "a", the name is one of a completely different gender whatsoever! And trust me, it's happened before!
lol! Of course it doesn't have to do with your old-lady memory, as you say! It only has to do with the name not being in the names database! ;)
