This book was published by Werner in 1919. All the information in the book had previously been gathered by Benjamin F. Thompson, the noted historian of Long Island, who died in 1849.
Thompson could trace his family roots back to the earliest days of Setauket, Brookhaven, Long Island and in fact was descended from a Satterly/Thompson connection.
According to Werner, all of Thompson's genealogy work, including the Satterly-lee-ley information was gathered together in one place when Thompson died in 1849. Werner surmises that Thompson had planned to publish the lengthy genealogical notes as an addendum to his classic book, The History of Long Island.
How Werner acquired all of Thompson's material is not clear to me. However, Werner evidently gained access to all of Thompson's work and published the genealogies himself. He comments that he didn't really do any additional research on the families to fill in the gaps between the 1850 material and his publishing date in 1919.
Also, we now know that there are several INaccuracies in the published records. I think that they came about in three ways.
First, much of Thompson's work was set down from the memories of the oldest residents still living in Brookhaven when he was gathering information. This was still more than one hundred years after Setauket and Brookhaven were first settled.
Second, most of the earliest records were written in "ye olde Englishe" and the type of inks they used and written word would allow for plenty of transcription mistakes.
Lastly, Werner himself may have erred in HIS transcription of information from Thompson's notes into his own book.
Since Thompson's earliest genealogical work became a part of Werner's book andcontained a very valuable look into the earliest Satterly-lee-ley families on Long Island, it has become one of the "foundational" references for Satterly-lee-ley and allied family researchers.
Goldie Satterlee Moffat Fowler copied the Satterly-lee-ley section ofWerner's book nearly verbatim in her Volume IV of her series of Satterlee-ly-ley and Allied Families History and Genealogies
THAT book in turn became foundational for many Satterlee-ly-ley researchers.
So both the accuracies AND INaccuracies of Thompson/Werner/Goldie's publications continue to be utilized in hundreds, if not thousands, of Satterlee-ly-ley family trees.
I understand that Thompson's original files are archived at the NYS Library in Albany, N.Y.
Perhaps someday someone will take the time to access those important documents and especially peruse the Satterly-lee-ley section. There may yet be some as yet undiscovered pearls in Thompson's work.
