I tend to, yes; I have a thing for memorization. It allows one to act much quicker than trying to rummage through books. There's plenty of stuff from the period though; the 'prophecies' (not actually prophecies of future events; they were actually just books and papers written on current events of the age), like the one that describes the conquest of Alba, lots of 'rolls' that number the soldiers involved (though they can vary, but the type of soldiers are consistent). I can help with the Welsh too, if you need that, but you seem to have that well enough in hand. The Welsh can logically share a great deal with Saxons (peasants and basic infantry would all look pretty similar), superficially (names and such would vary, assuming you used local names, but the appearance would generally be similar). However, Welsh were especially fond of skirmishers, and varied types of bowmen. The longbow DID exist (it had killed a Mercian king at Wansdyke in 825), so longbowmen are perfectly valid as a Welsh unit (and mercenary unit as well, Welsh longbows were hired pretty widely through Britain and northern Europe).
