Sir Lucan was one of the Knights of the Round Table. In the different accounts of King Arthur, Sir Lucan is always depicted as loyal and the last to leave the battlefield. http://en.wikipedia.org/wiki/Sir_Lucan
Personally, I really like this name. I came across it, while looking for a name that was a bit more original than Lucas or Luca. These names are beautiful, but a bit overused in my opinion. And that's where Lucan comes in. This name is especially great to use, if you've studied Latin or are interested in history. It's a strong, solid name, which makes me think of a smart, noble and heroic boy.
A famous bearer is Lucky Lucan, formally known as Richard John Bingham, 7th Earl of Lucan (born 18 December 1934). He disappeared on on 8 November 1974 after he allegedly murdered his children's nanny Sandra Rivett and attacked his wife. A lot of people believe he did it, but Lucan still hasn't been found and there are many theories around his disappearance. Lucan is now presumed dead. http://en.wikipedia.org/wiki/Richard_Bingham,_7th_Earl_of_Lucan

Given that Lucas and Luke are derived from a Greek name meaning "from Lucania," I see no reason why the Roman cognomen Lucanus (from which Lucan is derived) cannot mean the same thing.
I heard this name while watching 'King Arthur', There was a little boy with this name and I just thought that it was so lovely! I adore the name Lucas, but it's a bit to overused, But Lucan is perfect, Its strong and unique! Better than Lucas.
