For me it's Silas - it reminds me of the adventure programmes I used to watch as a kid. I think one of my first crushes must have been on a character called Silas.
I did suggest it for DS1 (vetoed by DP), but thinking about it I wouldn't want to call my son Silas and I can't really explain why.
Does anybody else have a name that they wouldn't use, but really like nonetheless...?
