First name for middle name Gracen-girl

We are team green this pregnancy (not finding out gender until birth) and I love the name Gracen. However we know several people whose kiddos first names are Grayson. My best friend of almost 14 years is Grace and I would love to use Gracen after her. I cannot find any names that I like with Gracen! Our daughters name is Lynden so I’m being picky about it flowing together 😂 TIA!
