One thing I considered when I named my kids was the Googleability of their names. Our last name is common enough that if I give them common names they would almost never wind up on the first page of Google. And my most unusual child’s name is actually shared with a famous person. (Not to mention also mistaken for a hoity-toity misspelling of a girl’s name due to rampant Biblical illiteracy.)
But maybe your last name is unusual enough that that your kids will be Googleable even if you name them David or Elizabeth.
And who knows what “Google” will look like in 40 years. It’s possible that someone typing the proposed name into a search engine could find this very page!
