My boyfriend's family has a tradition of first borns getting names that start with 'D'

We had some choices picked out that have been vetoed and decided if we can't find anything else we would go with Donovan but I'm really not happy with it! I don't want Donny as a nickname and I just feel like it's gonna be inevitable :(

Other names we liked but won't use are Dashiel, Daxel, Dreydan, Daedrian, Dreyik.. We kind of like Denver but I don't think I could do a place name

I really like unique names, does anyone have any suggestions?! Our baby is a boy :)
