I wonder if one of Effie's sources might have been "History of Long Island from its Discovery and Settlement" by Benjamin Franklin Thompson, M.D., Counselor at Law, lst Edition, Jan 1, 1839, Published by E. French, 146 Nassau St., NYC (3 volumes) Stated: New Utrecht was settled by 20families from Holland in 1654. In 1660 they applied to Stuyvesant and were, in 1662, granted a patent confirming the purchase of their land. Another patent was given them in 1666, which described the town's boundaries and an old map showed its location.Thompson's 3rd ed. shows "New Utrecht" and a place called VAN PELT Manor.There doesn't seem to be any real proof that a Van Pelt was one of the original owners. The first patent in 1660 shows no names, and if it did, would probably show names of agents for the applicants. These findings came to me second hand from the researcher.If you have the means to check further it might be interesting.
