I love this name. It's so, well - Sincere!Virtue names in general have positive connotations with polite, well-mannered, and honest people. I also like the fact that this name works at all ages and is not strictly a babyish or childish sound. There are a few nicknames which could be made to work with it also: Sincie, Cerie, Cere...Personally, I would use this as a middle name alongside a classic first name, but I also like it as a first name.
