Hồ Quý Ly (c. 1350 – c. 1410).
Origin and background.
The appearance of the Hồ family name, origin and background can be traced back to a clan from 10th century Zhejiang, which was then in the midst of the Five Dynasties struggle.
From Zhejiang, the family migrated south until they established themselves in northern Vietnam.
Hồ Liêm, Hồ Quý Ly's great-great-grandfather, moved further south and settled in the province of Thanh Hóa (about 100 km south of the modern city of Hanoi).
Some historians bring attention to the fact that Hồ Quý Ly is also known as Lê Quý Ly.
In his childhood, Hồ Quý Ly was adopted by Lê Huan after whom he took the family name.
He did not change this Lê last name to Hồ until after he had deposed the last king of the Trần dynasty.
Because of the short span of the Hồ dynasty and the tragic circumstances he brought upon the country, under the juggle of the Ming, the family name "Hồ" was disgraced thereafter.
However, historians have attributed to Hồ family quite a few notable scholars, dignitaries, and government officials under both the Lý dynasty and Trần dynasty.
