Have you given your flagship (or any other ship for that matter) a custom name and if so, what was it?

So far I've had a Ship-of-the-Line called "Sylvana", after "Last Exile".

Edit:
And now I'm running around with a Royal Sloop called "Margaret Evans" (of the Blue Star Line, yes), a SotL called the "Sylvana", and the Royal Galleon that I took from Montalban (with the Royal Sloop) renamed "Aldonza Lorenzo". Which is the name of Don Quixote's love interest. Since the book was published in 1605, and is the most popular Spanish book ever, there's pretty much no way that the Marquis would not be aware of the reference. It's enough to make me hold on to that ship.
