I am looking for any info on the surname De Glopper. I have info that Jacob de Glopper arrived in N.Y. on Rose Standish Sept. 13, 1849 from Zeeland. He came with Johanna, 7, Martinus, 4, and Pieter 1. Martinus was my husband's great-grandfather and settled in Grand Haven. He married a woman named Maria. Martinus, Maria, and many of their childrenare buried in Grand Haven Lake Forest Cemetary but I have no idea what happened to Jacob, Johanna, and Pieter. Any information about any De Glopper would be greatly appreciated.
