Baylor is a college, and if I am correct, so is Brighton. I would steer clear of using both in a sibset. Jameson reminds me of Jamestown as well as the ever so trendy surname as first name.
Holden gives me that vibe as well, although it is also literary so I don't mind it as much.
Hilary bothers me as a boy and a girl name.
Sterling reminds me of Starlings, which are horribly mean birds.
