Thank you very much.
I will be off line for a few days (it's our Thanksgiving holiday here). If you are interested, I can send you the Slingerland tree that I have dating from Willem (b. abt. 1674) and m. to Marijte Pieters (b. abt 1675). I also uncovered some branches along the way. I just recently found the approx. grave sites of my Great-Great Grandparents, John Slingerland and Anna Maria Petronella Ziegler Slingerland -- in Green-Wood Cemetery in Brooklyn, NY. However, there is no grave stone or other marker, so when the weather gets warmer, I have to try to locate the grave (there are 4 family members buried in the grave, the 3rd may be my great-grandmother's sister, but I have not figured out relationship of the 4th). My great-grandmother (Johanna W. F. Slingerland) was buried in New Jersey, but I have not learned why, since she died in New York City.
