What other historical figures transferred their power into

Does the timeline of Nioh match up with the real timeline of events? Like, did William Adams come to Japan before Sekigahara?

With William being a samurai, did he ever actually see combat or did only have samurai as a title?

Adams arrived in April 1600, the battle was in October 1600. He certainly wasn't trained as a samurai; his position was more akin to an oyatoi gaikokujin.

William never saw combat, he served in an advisory role for foreign affairs and trade.

Real-life Adams was only a sailor who basically became a politician by sheer accident. He was basically kept as a glorified hostage by Ieyasu because he wanted an insight into Western shipbuilding and tactics.

Nioh's William on the other hand is an Irish mercenary who fought his way into the picture.
