it's weird but my fiances nameis DeMarkus and I love his name. pronounced more like Duh-Markus
Damien, Daryl, Dylan, David, Dweyn, Devon, Drew
Dean, Derek, DeSean, Devon..
Daylon, Deagen, Dominick, Donovan
Dominic, Dakari,denim,...wow it is harder then I thought.
Devin, Derrick, Dylan, Donovon. That's all I can think of! Lol
The only one I can think of right now is D'Artagnan from the the Three Musketeers haha
If you're not set on having the "d" be separate from the actual name and you just want it to start with D, then Daniel, David, Darren, Dorian, Damon, Darien... hope that helps!
