Pirates, a Princess and a Knight (probably NOT in shining armor)

Here's a brief story about my 11th Great-grandfather, Sir John Henderson 5th of Fordell.  Born in 1605, he went to Africa as a young teenager, was captured by Pirates - escaped with the help of the Princess of Zanzibar, returned to England to fight with Royalist forces in their Civil War and was Knighted by King Charles I.
