Following your 'bloody: advice, I will guess Disney, altho a part of me really wanted to say it's just plain old D standing for nothing. But we'll go with Disney!
My guess is it's DAVY or DAVID, LOL. I know that's technically "two" guesses, but my point is, the name is after Davy Jones, whichever version of his name. So, if it's either of these, hopefully my answer qualifies. ;)
"Daphne" - a laurel, or "Delaney" - descendant of the conquerer, or "Dakota" - beloved friend - can't decide, but beautiful baby - looks like her brother! Congratulations to all!!!
