My wife didn't care for her initials. Her maiden name was Griggs, though....and then she married into my last name on top of it. (Yeah, I know, "Eeeeew, Gross!")
There were so many things to consider with naming the kids that we didn't even consider initials until we named them. So we ended up with Kiera Elise and Alannah Ruby....
Of course, thinking about this kind of stuff takes me back to the "I Married Marge" episode on the Simpsons, when they came up with Bart's name....
