I like it. The only trouble with
Madeline is the pronunciation. Some say mad-a-line, some say mad-a-linn. I like both, so it's fine, if a bit confusing.
I used to really dislike this name because I went to school with a
Madeline, called
Maddy, who was a bully. She was the only
Madeline I knew for years. So for a long time it made me think of "mean girls from the 90s". But luckily that association has faded and I can appreciate it now.
