Mori Ranmaru (1565- 1582) is a Qinghe Genji, that is, Genji was founded with Yuan Yi Long as its ancestor. His father is Nobunaga's retainer Sen Kecheng, his brothers Sen Kelong and Mori Nagayoshi, and his younger brothers Sen Fangwan, Sen Liji, Sen Zhongzhi (later the first generation of Jin Shanfan) and others.
Both of them are ODA family ministers, and it is normal for them to have the same and similar family background. They are all the second generation families developed by Oda family, and the similarity in form is for better battlefield distinction.
Cheng Zhen Hexagon (152 1 year-1April 598 19) was the famous name of Nanjin River and the head of the Hexagon family in the Warring States Period. Hexagon Cheng Zhen's real name was Hexagon Yixian. After his father died in 1552, Hexagon decided to take over the position of director of Hexagon. Because Hexagon Cheng Jin was brave and good at fighting, but he was ill-considered, he not only became an enemy of Azai Nagamasa, but also launched 20,000 troops to attack Azai Nagamasa in 1560, but was defeated by Azai Nagamasa's surprise attack at night. Therefore, Hexagon Chengzhen gave the position of supervision to his son Hexagon Chengzhen and became a monk. However, Hexagon Jisi is a more stupid governor than his father. 1563, Kiji Hexagon caused a commotion in Kannonji by killing Kenfeng Goto, an important minister of Hexagon family, which led to internal division of Hexagon family. 1568, Nobunaga sent his troops to Beijing, and the Hexagon Formation Town and others knew that they were defeated, but they still fought against the heavenly army. So Nobunaga attacked Kannonji, the hometown of Hexagon, and the Hexagon family also perished.
If it is a crane pattern, it is also very common. There are thousands of samurai families in Japan, and it is inevitable that there will be heavy patterns, as well as many sub-patterns and giving patterns. Sub-pattern means that each family uses its own family pattern alone, or slightly modifies its own family pattern to show the difference. Giving pattern means giving its family pattern to meritorious ministers and allowing them to use it on specific occasions. Plants are the most common family in Japan.
These three are all related to the same name, nobunaga!
