Sandra Bullock's choice of Bardo as her newly-adopted son's middle name puts the spotlight back on the O names - names that begin, end, or otherwise emphasize the letter O.
Over at nameberry we always loved the O names and have taken an ever-expanding view of the category since publishing our first name book, Beyond Jennifer & Jason, in which we (shockingly, at the time) declared names that end in O such as Theo and Milo to be "So Far Out They're In."
We wrote a blog last year on popular O names, ranging from Leo to Inigo, Alessandro to Juno and including such newly-hot not-technically-ending-in-O girls' choices as Harlow and Margot.
But Bardo wasn't in there - though it was included on nameberry, as a German saint's name (he was the 11th century bishop of Mainz) and also an Aboriginal name meaning water.
Bardo is also a Buddhist concept meaning "intermediate state" - significant, many say, because of Bullock's marital woes and decision to divorce, announced at the same time as her baby's adoption.
Wikipedia lists the Six Bardos for those who want more illumination, as well as other people and places that have a relationship to the name. In a more earthly realm, David Boreanz named his infant daughter Bardot, as in the surname of French star Brigitte.
