Castiel raised by/is the child of another angel?

[amybutler1800.livejournal.com]

Okay so I've read a couple of fics where Castiel is either raised by another angel as a fledgling (most of the time it's Gabriel), and one or two where he is the child of two other angels (through them combining their grace, ect.). These are the fics I've read like that so far:

Blessed is his child, by ameonna1

Of Seraphs and Men, by daksgirl

the Gift by NHMoonshadow

Of Baby Angels and Older Brothers, by I am psycowriter

So yeah, does anyone know any other fics like this? It'd be great if it also included moments after Castiel has met Dean and Sam.
