Interesting question. :-) Because I trace ancestry to this family, specifically to Abigail Davenport, who married Henry Oostrom, I've puzzled over the origins of these Davenports (and why they are sometimes called Danforth/Danford and sometimes Davenport), but I have not researched Abigail's Davenport ancestry.
As near as I can tell, there's no evidence that any of the Davenports were settled in New Netherland by 1674 (so they aren't New Netherland Settlers and their children aren't New Netherland Descendants), but we can treat the family members who were in the New Netherland area before 1700 as members of the New Netherland Community. Accordingly, I just added the template and the project account to the profiles for William, his wife Mary, and son Thomas.
That Thomas Davenport and His Descendants book seems to be a good starting point for this family's genealogy (indeed, it looks like several of the existing profiles for family members were originally based on this book, even if the book isn't cited). However, because I encountered some serious errors in the original profiles for my ancestors who are documented in that book, I caution that we need to seek primary records for these people to confirm, supplement, or possibly refute information found in that book. At least some of these people's life events (such as my ancestor's marriage) were documented in church records -- see https://www.wikitree.com/wiki/Space:Baptism_and_Marriage_Records_of_the_DRC_in_America for advice on finding church records for this region. Pat Wardell's document about the Davenports, available via https://www.wikitree.com/wiki/Space:Early_Bergen_County_Families , may be also be a good resource. And please stay in touch!
