I doubt it.
judging by those dates and the appearance of the men in the photos....I'd say these men are part english. THat's the way it usually worked back then. THE british ruled the world and the ruling class of all the nations that the british had dealings with became "semi-british" not just in manner and behavior, but also in genetics.
"I doubt it." Then you know very little about the Ainu. The Ainu were the original Samurai. Ancient, seldom seen, Japanese paintings show the Samurai as tall, light skinned and hairy people. They were the rulers in their peak. Some say the Japanese custom of 'white face' comes from this period and was an effort by the lower classes to emulate their rulers.
