The first humans to enter Beleriander were called Edenites by the elves to distinguish them from those who arrived after the Battle of the Blaze. The latter is known as the "Coming from the East". The Edenians had three families: the Beau, the Marrych, and the Haradin.

The first patriarch of the Beo family after entering Beleriander was Balan, and Finrod gave him the name Beo. His family had a long history of loyalty to Finrod. They then moved to the fiefdom of Radlos. Beo's son, Balan, gave birth to Bolon, and Bolon's son was Boromir, who in turn gave birth to Brigor. The two sons of Bregor were Bregoras and Barahir. Bregoras had two sons, Baragond and Beregunde. Their daughters are Murwen and Leanne. Balahir had a son named Belen.

The first patriarch of the Ma Rui He family was Ma Rui He. His son was Malach, and Magor, the son of Malach, gave birth to Hathor, whose only son was Hado. Later, the Marrich family was also known as the Hado family. Hado gave birth to two children, Gardo and Gloritil. Gardo raised two sons, Hulin and Juao.

The House of Haradin had no patriarch in the earliest days. It wasn't until they were attacked by Orc during their time in Shagailian that Haldad became the patriarch of House Haradin. He had two children, Hareth and Halda. Hareth had no children because she was never married. Her brother left behind a son, Haldan, on his deathbed. Hardan gave birth to Halmir. Harmir gave birth to a son, Hardir, and a daughter, Harris. Haldir married Gloritil of House Hado, and Harris married Galdo of House Hado, bore him Hurin and Juo. Hardir gave birth to Handir.

The above is the situation of the major human families before the Battle of the Sudden Fire.
