3. Suo-Oshima Yashiro-jima “Aoki Genealogy”
Suo-Oshima Yashiro-jima “Aoki Genealogy” begins from the following sentence
“Home country Mino castle owner
Aoki's original is
the posterity of the Tajihi clan’s twentieth generation
Aoki Musashinokami Naokane’s fifth generation’s grandson
Okochi Shuri Aoki Izuminokami Motoyuki”
This genealogy, which seems to be the final copy of the early Meiji period, has lost records before the end of the Muromachi period (Sengoku period).
Such genealogy is common, and genealogy is written on Japanese paper as a recording medium, but most of them are divided into "scroll" format and so-called "booklet" which is folded in half. Each has its own advantages and disadvantages, but a "scroll" is more convenient for drawing a genealogy line that shows the correlation of blood lines, while a booklet form is convenient for writing individual records, letters, and important documents.
The Aoki genealogy is in "scroll format", so it contains a genealogy line. Some people refer to the format with genealogy as "(keizu) genealogy" and the one without genealogy line as "(keifu) genealogy". Some submission genealogy, such as the daimyo family, has both formats.
The Aoki genealogy begins at the end of the war period, so there is no previous record, but only beginning sentence
“Home country Mino castle owner
Aoki's original is
the posterity of the Tajihi clan’s twentieth generation
Aoki Musashinokami Naokane’s fifth generation’s grandson
Okochi Shuri Aoki Izuminokami Motoyuki”
became hint. Let's reinforce it a little from other literature.
It says “Home country Mino castle owner”. But it’s not the Mino castle. It’s a castle in Mino country (Gifu prefecture).
It says “the posterity of the Tajihi King’s twentieth generation, Aoki Musashinokami Naokane”.Tajihi king is the Tajihi Koou (Tajihi) (624-701) who is fourth generation descendant of Emperor Senka (467-539). He is called the Tajihi king because he was given the surname of the Tajihi.A person who is twenties descendant of the Tajihi king moved to Mino Province, and he was called Aoki Musashinokami Naokane, and it seems that he had a castle under the Toki clan of Mino guardian at that time.
It is said that the origin of Aoki's surname was taken from Aoki, Iruma-gun, Musashi Province. Since Iruma-gun is new name of Koma-gun, it is said to have been called Koma-gun because it gathered the Kokuri people on the Korean Peninsula. Kokuri became an enemy of Japan during the Battle of Hakusonko, so I'm not sure if the people of Koma-gun were brought in as prisoners of war or, conversely, those who fled to Wakoku (Japan). The people of Aoki in Musashi Province are believed to have been responsible for managing these people. Some of these families may have come to Mino Province and named themselves Aoki Musashinokami Naokane.
The system that refers to Aoki is large, and there are two types, the Tajihio style and the Fujiwara no Kamatari style. Since person from Tajihio is adopted in the Fujiwara clan, the Tajihi clan seems to be the mainstream.
Both strains are based on Aoki Musashinokami Naokane. This person served the Saito Dosan family, who betrayed the Toki family, and after the days of Nobunaga and Hideyoshi, the Aoki group who served Ieyasu later became the Asada feudal lord Aoki family in Settsu.
On the other hand, Aoki on Yashiro (Suo-Oshima) Island seems to be a different stream of the same Mino Aoki, and is called Okochi Shurinosuke Ietsugu, the grandson of Naokane's fifth generation. It is said that Ietsugu went to Kyoto and learned swordsmanship.
In the Aoki story, Aoki's surname is Kitakochi, but this seems to be a pseudonym of the Hideyoshi era. Many of the houses that were in a hostile relationship during the Hideyoshi era have been renamed for fear of exploration. After Hideyoshi died, there are many cases where he returned to his real surname.
The Ono family on Yashiro Island in this blog has been renamed Tomoda, and the Hiraoka family has been renamed Oka. Renaming is not a surname because it is a temporary act to hide yourself. It is well known that the Sishi (anti edo government samurais) at the end of the Edo era used many nicknames to escape the pursuit of the authorities.
If Aoki Shurinosuke used the pseudonym of Okochi, it may be related to the Okochi family, a vassal of the Mori clan, but it is within the imagination range because the Okochi document has not been examined yet.
Let's explore these together.
