Anyone wanting to start a Knickerbocker genealogy needs a place to start. I can offer two:
The first is The New York Genealogical and Biographical Record, Volume XXXIX, 1908. If you use your favorite search engine to search the term in bold you will come across a number of downloadable copies. This is a great place to view or download a copy. If you choose to get a copy, find page 33 and on it you will find an article called “The Knickerbocker Family” by William B Van Alstyne, M.D. The article starts off with Harmen Jansen Knickerbocker the first Knickerbocker ancestor in America and goes to page 42 before the genealogy seems to end. It’s picked up again in the middle of page 116 with Elizabeth Knickerbocker and comes to a stop, again, on page 125. The genealogy is continued twice more at pages 179, 277.
The article continues with the series The New York Genealogical and Biographical Record, Volume XL, 1909, which you can download or view here. The Van Alstyne Knickerbocker genealogy continues on page 55 then resumes again on page 100.
I like keeping copies of things so I can easily refer to them later. I use multiple devices (computers at home, work, iPad, etc) so I like keeping things such as copies of the NYGBR on Dropbox so I can access then anywhere. You can get a free Dropbox account by clicking here.
If you don’t need or want a copy you can go to the Knickerbocker Family site (www.knic.com) and browse through to the genealogy section. A direct link to a web version of the Van Alstyne Knickerbocker genealogy is here.
