Joshua 17:1, 5-6

Then land was given to the tribe of Manasseh, Joseph’s first son. Manasseh’s first son was Makir, the father of Gilead. Makir was a great soldier, so the lands of Gilead and Bashan were given to his family.

So the tribe of Manasseh had ten sections of land west of the Jordan River and two more sections, Gilead and Bashan, on the east side of the Jordan River. The daughters of Manasseh received land just as the sons did. Gilead was given to the rest of the families of Manasseh.
