Margaret born 1801/1802, d 1874, married John Shafer (b ca. 1805 -- son of 
John Shafer Sr. and Mary Van Vliet).  Both Margaret & John buried Bethlehem
Baptist Cemetery on Baptist Church Road, Pattenburg, NJ.  According to
DARYL_HOFFMANN_918@comcast.net ... the church is all but collapsed --
this cemetery is oft referred to as the Van Syckle/Syckel Martin Cemetery
(and they maintain same).
