Girl Middle Names??

First Names are Isabelle and Thea. Last Names are Burgess. **I want to use both names as FIRST names. :)

Boy Bonus: Furst name for _____ David Burgess. Entertaining the idea of Grayson David Burgess but would like some more.

Note: We have Sophia Jonae, Landon Mark-David (both from previous relationships) and Zane Orion (named before I met my husband but we have raised together since 4weeks old). All boys in my husbands family have David as middle name.
