Perhaps Mrs. Rush, ‘Katherine’, had a role in the selection. Just who calls their wife ‘Katherine’ anyway?
Someone who married a woman named '...Katherine'?
Just playing with you, bramps! I have a similar name and people call me that name - no nicknames. I did not ask them to go by any nickname and they just seemed to think my full name was ok.
Of course, they call me some other names when I get my "conservative" dander up!
