You seem to like varying naming styles.
I see Harrison and Scarlett as classic and traditional names.
Not sure how I see Reese or Reagan. Not traditional but not really trendy either (I know quite a few Reagans between newborn to 35).
Briley screams trendy to me. I first encountered a similar name, Brailee, about 5 years ago and I loved it (although it is the name of my DH's cousin's kid so it was immediately off the table). Over time I have realized how trendy and almost childish (with the "ee" ending) it sounds. I've definitely backed away from names like that since (although I still have Brinley and Brilyn on my loooong name list, they are just on there and are not something I would seriously consider).
Since I REALLY like Harrison and I do like a few of your girl names, I'll throw some out there that I like as well (I'm allll over the place. lol)
