So Henry was raised in Southern England, yet he is either Mediterranean or African...so you are not really sure about Henry just making up a story? Correct?
“Henry” can lie all he wants to.
His DNA and the minerals in his teeth and skeleton are fixed and not subject to his sophistry. Since the minerals in his remains say he grew up in southwestern England around Portsmouth, the underlying question is how did his family (or at least the Mediterranean/African component) come to be there?
Thought the painting of the Mary Rose looked like another famous ship of the era, the Mayflower. So I looked them up to compare their specifications (such as they are):

Mary Rose and Mayflower were both carracks in basic design with the warship being about 10 foot wider in the beam and 10-20 feet longer over all.
Of course, Mary Rose was fitted out as a warship and Mayflower was a cargo vessel. What was really surprising was the very large number of sailor and soldiers embarked on the Mary Rose and the astounding number of cannons she shipped.
The article also has a good discussion of the ship’s service history and the various theories of why it sank.
Europe had small populations from Africa, and I explained it clearly enough for any reasonable person to understand what I wrote.
