Indian Mills, formerly known as Brotherton, is an unincorporated community located within Shamong Township in Burlington County, in the U.S. state of New Jersey.

[6] In 1756, the British colonial government appointed commissioners to resolve disputes between white settlers and the Munsee Lenape native to the Washington Valley.

[3] In 1757, the "New Jersey Association for Helping the Indians"[7] wrote a constitution to expel Munsee Lenape native to the Washington Valley.

In 1780, Munsee Lenape community leaders of Brotherton, native to Washington Valley, wrote a community treaty[9][8] to oppose selling any more land to white settlers:Be it known by this, that it has been in our consideration of late about settling of White People on the Indian Lands, And we have concluded that it is a thing which ought not to be, & a thing that will not be allowed by us, that of Renting or giving Leases for said Lands, hereafter, no, not by the proprietors themselves without the consent of the rest much more by those who has no Claim or Rite here ... We have come upon those resolutions we hope for our better living in friendship among one another, it may be that there is some which does not like white people for their Neighbours, for fear of their not agreeing as they ought to do.

it might be about there children or about something they have about them we know not what, Again it may be the white Man may do something either upon Land, Timber or something else which some one of the proprietors would not like & from thence would come great deal of Disquietness, & many other ways which may plainly be seen into, by those that have any sense or reason—
