Albert Barnes Commentary Joshua 17:2

"So [the lot] was for the rest of the children of Manasseh according to their families: for the children of Abiezer, and for the children of Helek, and for the children of Asriel, and for the children of Shechem, and for the children of Hepher, and for the children of Shemida: these were the male children of Manasseh the son of Joseph according to their families." — Joshua 17:2 (ASV)

For the rest ... - that is, for those who were not settled on the east of Jordan.
