Records of the Reformed Protestant Dutch Church of the Town of Flatbush, Kings County, New York, 1677-1872, compiled by Frank L. Van Cleef, Microfilm, LDS FHL Film# 17663 items 1-5, Located at the LDS Family History Library, Salt Lake City, UT, viewed Sept. 2006; Various dates are listed for "use of the shroud" and for graves for various members of Christoffel Probasco's family. Since no records for an Abraham Probasco have been found for his time period, I estimated he was one of the children that died young.
