Some fonts I found on the Internet:

Font 1: Devious

This one doesn't exactly have a certain lettering style for each letter. It veers more towards freestyle capitals with freestyle flamboyance on every second or third letter; the ones with a straight line pointing up or across.

Say I was going to write the phrase Dolphins are evil and not to be trusted.

Font 2: copperplate

Used in the early 20th century quite often. Quite flamboyant, but strict rules on writing it. Each latter takes quite a long time but it's worth it. I use it sometimes.

Font 3: angry capitals

This is how I write, most of the time. It's a good font. Fairly readable and quick to do. 

Well, I think I took too long to say it, but the point is that it's easy to fake your handwriting. It's very easy to copy things and forge signatures. Just because it's written in someone's handwriting does not mean it's genuine. A proper calligraphy artist can very easily copy and fake things.

Writing using proper calligraphy is generally used for fun, though, or as a way of disguising your handwriting. The flamboyancy is excellent and taking time over it, observing details, is fun. I don't know. It's fun for me but then yesterday I spent an hour and a half staring at a wall, so maybe taking your time to become a full-on expert at calligraphy isn't quite your thing. Still, though.... It's fun.
