@selah-chelyah and everyone: G. A. Henty is good at plotting. Admittedly, he put a lot of work into making one plot, which he then used for every single book of his, but he wouldn’t be the only writer to do that. Once in a while he’s not terribly bad at characterization. However, his historical accuracy is conspicuous by its absence, as a professor of mine says of students who don’t show up to class. His books are not good references for historical accuracy and have no place in that kind of bibliography.
In any case, it is always best to use primary sources for any period, and a work of historical fiction, however well-done, will only be a secondary source at the very best. If it has a good bibliography you can certainly use it as a starting point for further reading, but that’s not quite the same.
Do your own research and don’t believe the English of the 11th century (however good their textiles actually were — and they are amazing) had access to velvet, that delightfully anachronistic material.
(It wouldn’t be invented for another few hundred years.)
