I think it fits well. I like the "blind" meaning. I feel it gives the name strength and depth. Plus there are so many great blind musicians.
I wouldn't say it's too religious, but I don't know many Catholics. I guess the only
Cecilia I know is Catholic!
Cecily sounds better as a middle name for your other choices.
Cecily is also a cute first name.
Cecily Augusta Stewart Lastname AWWWW
