I figured I’d go through and pull out all the proper names and so forth; this has ended up quite long and I have hidden the less relevant bits under details tags so it looks less intimidating 
Chapter One
Chapter one hits you in the first few pages with a blizzard of historical names and references which are probably never going to come up again and so are pretty safely skippable. I have pulled up a little info from Wikipedia below for them. The author doesn’t really expect you to know this stuff in advance in most cases, but I always find sentences packed with historical names a bit painful to read anyway. I hope the notes might help a little.
I have spoiler-tagged the details for the character names, but not all the historical stuff (which I don’t think is particularly spoilery).
The list of actual book characters is thankfully much shorter and I list them separately and first.

Historical notes
These are just some bits of background information that I thought might be helpful if you’re not too familiar with this period of Japanese history.
When are we?
The novel is set at some point in the Edo period, which is the period when the Tokugawa shogunate had complete control of the country, from about 1600 to 1868. The social and governmental system was pretty stable over this time period, so it doesn’t make much difference exactly when in it we are. I find that historical fiction set in this period mostly uses it as a backdrop for storytelling, and don’t have a lot of “cameo appearance by real historical figure you’re supposed to recognize” or “real historical event affects the plot” (much as Westerns use their setting for storytelling and don’t need the reader to be familiar with the exact details of the expansion of the US frontier in the 19th century). A vague idea of a society with samurai, merchants and peasants, with feudal domains and a central shogunate, should be good enough.
勘定奉行
Head of the financial/accounting offices of the clan. This is a pretty important position that 将左衛門 holds. Each individual clan has near-complete autonomy within its territory, and it taxes the peasantry on their rice crop, carries out public works, pays levies to the central shogunate authorities, and hands out a stipend to every samurai. So its finances are the local government finances, effectively. If the domain is small or doesn’t have much productive land (or there’s a bad harvest) then making ends meet can be tricky.
参勤交代
Every clan lord is required by the shogunate to spend alternate years in Edo (and their wives and children must remain permanently in Edo), so they’re not even in their own lands much of the time. This policy was set up as a precaution against rebellions.
Archery traditions
These are all real historical traditional schools of Japanese archery, so the author is showing off that he has done his research by listing them all. I think they are highly unlikely to be plot relevant except for the first two. Wikipedia has a chart of 日置流 development which shows the relationships between the various subschools: https://upload.wikimedia.org/wikipedia/commons/4/4e/Hekiryu_keizu.PNG
