ますます迷宮に彷徨う（笑）家系史探究の旅路・・・。
　わたしの家系に伝わっている一族の古文書「原氏由来の事」を1815年に記述した六世の祖・三木寛蔵が探訪した一族由縁の故地・広島県河内町入野の再発掘途上。
　1997-8年当時、次兄がその文一族の古文書を送った経緯から現地調査してくれた河内町教育委員会の「報告」書類を再精査している。その調査で訪問してくれた入野に残る同姓（原氏）の家での調査記録中に、そのお宅の「家系図」があり、それとじっくり対話を続けているのです。
　もう２ヶ月以上眺め続けているのですが、いまのところ頓悟できません。
　しかし確認しようにもヒアリング対象の方はすでに他界。また調査記録者の方も、健在だとしてもすでに100歳近いご高齢。なかなか確認の術を見いだせないのです。しかし悶々としていてもラチが開かない。本日ブログでそ一端を書き記してみたいと思い定めた次第。
　その家系図の一部が上の写真。調査時に撮影された家系図写真。かなり「虫食い」も見られ「保全」が心配ではあります。その下は広島藩公式文書「芸藩通志」での当該地広域地図。
　以前書いたように、わが家系の九世の祖「平七」がこちらの家系図にも記載されている。この平七の代、浅野藩の所務役を務めて百姓一揆で焼き討ちされた旨の広島藩の公式記録がある。
　わが家系図ではその子・八世の祖はたった１人だけ伝承記録されている。一方こちらの家系図では当家の八世の祖の人名は不記載。想像すれば、わが家系はその焼き討ち時点前後に入野からは50km以上離れた福山藩領・松永の塩田に「分家」して、生き延びる道を見出していったと考えられるのです。
　一方「本家」筋のこちらの一統は入野に残り、いつかの時点で上に掲載の家系図を再度作成したと想像できる。焼き討ち前後時期に記憶を喪失しないように「再編纂」したものと思える。
　そしてその家系図には記録起点として「文和４年」1355年とある。（この西暦年記載は撮影後、調査記録の教育委員会の方が写真上にメモ書きしたと思われます）
　この家系図では起点がいまから671年前とされ、一族の出自は「秋田信濃守・原」氏という記載。〜右の書き出しの「信濃守」が左側では「濃信守」と誤記されている。単に表記ミスと思われます。〜
　WEBで確認すると符合する「秋田信濃守」という大名家は存在している。源氏による奥州侵攻で攻められた「安東氏」に繋がってくる流れ。
　・・・という意想外の歴史時空間にジャンプさせられてしまった。さて？

【A Time Leap to 1355? The “Family Tree” of a House with Local Roots…】
A “family tree” confirmed during the Kawachi Town Board of Education’s 1997 field survey in Irino. The record’s starting point is marked as 671 years ago. Re-verifying the survey is also difficult. …

　Wandering deeper into the labyrinth (lol) on my journey exploring family history…
Currently re-excavating the ancestral lands of my clan in Irino, Kawachi Town, Hiroshima Prefecture—the very place my sixth-generation ancestor, Miki Kanzo, visited while compiling the clan’s ancient document “The Origin of the Hara Clan” in 1815.
　I’m re-examining the “report” documents from the Kawachi Town Board of Education, who conducted a field survey in 1997-8 after my second eldest brother sent them the clan’s ancient documents. Among the survey records from Ino, where they visited a house bearing the same surname (Hara), there was a “family tree” from that household, and I’ve been having a long, deep conversation with it.
I’ve been staring at it for over two months now, but I haven’t had any sudden enlightenment yet.
　However, the individuals I could have interviewed have already passed away. Even if the investigator were still alive, they would be nearly 100 years old. I find it difficult to discover a way to verify the information. Yet, brooding over it won’t get me anywhere. I have decided to write about this matter in part on my blog today.
Part of that family tree is shown in the photo above. It is a photograph of the family tree taken during the investigation. It shows significant insect damage, raising concerns about its preservation. Below it is a broad-area map of the relevant region from the Hiroshima Domain’s official document, the “Geihan Tsūshi.”
As I wrote before, my family’s ninth-generation ancestor, “Heishichi,” is also listed in this family tree. Official records from the Hiroshima Domain state that during Heishichi’s generation, while serving as an official for the Asano Domain, he was burned alive during a peasant uprising.
　In our family tree, only one descendant is recorded as the eighth-generation ancestor. In contrast, this family tree does not list the name of the eighth-generation ancestor for this branch. It is reasonable to imagine that our family branch, around the time of the burning, established a “branch family” in the salt fields of Matsunaga within the Fukuyama domain, over 50 km away from Irino, finding a way to survive.
　Meanwhile, the “main branch” lineage here remained in Irino and likely recompiled the genealogy shown above at some point. It seems they “recompiled” it around the time of the burning to preserve their memories.
This genealogy lists “Bunwa 4” (1355) as its starting point. (This Western calendar year notation appears to have been handwritten on the photo by the Board of Education researcher after the photograph was taken.)
　This genealogy places its starting point 671 years ago, recording the clan’s origin as the “Akita Shinano-no-kami Hara” family. ~The “Shinano-no-kami” written on the right is mistakenly transcribed as “Nōshin-no-kami” on the left. This is likely simply a notation error.~
　Checking online confirms the existence of a daimyo family named “Akita Shinano-no-kami.” This lineage connects to the “Ando clan,” which was attacked during the Minamoto clan’s invasion of Oshu.
…And just like that, I was transported into an unexpected historical time-space. Well then?
