Anthony retired as a priest in 1886, after being employed as a farmer, and subsequently worked with Daniel Garrison Brinton on a dictionary of Munsee/Lenape, visiting Brinton in Philadelphia in 1886 and 1887 in his ancestral Delaware Valley, and Brinton also consulted with him on the Walam Olum, which he believed to be genuine. Anthony is the source of the etymology of Manhattan, which was named after a stand of hickory trees used for bows in the south of Manhattan.[1]
