double first names ! HELP!

Jessika • ♥️ 30 year old mommy to 4 sweet babies 3 on earth and one in heaven (born sleeping at 31 weeks 6 days)
I have a son who is 4, he has a double first name which I picked and I love! 
I have a double name for if this little one is a girl but I need boy ideas! 
I really am set on keeping all my Little's with double names! 
Any ideas? (: 
Thank you ! 
P.s. Son is DavidRyan if that helps!
