To all; In working on the Van Duyne family of Morris Co., a puzzle arose concerning an entry in the 1870 Morris County census. I had accounted for most of the Van Duynes listed in that census with regard to the Van Duyne family tree; but an entry for E.E. Van Duyne on page 27 for Boonton Township could not be pinned down. I had photocopied each instance of a Van Duyne found in the microfilm record and thus had a physical record of every Van Duyne and adjacent tallied individuals both preceding and following the targeted individual or family. E.E. Van Duyne’s record was difficult to read, The gender box was a mess because, apparently, both “M” and “F” had been inscribed in the original record making its decipherment impossible. The occupation appeared to be “House Repair”. There were six adults listed in the dwelling, four of the males involved in the harness industry, one female keeping house and the mysterious E.E Van Duyne. Three of the listed adults were Hopkins and three were unrelated, pointing toward the conclusion that the three non-Hopkins (including E.E.) were boarders. Further directing me was the thought that E.E. Van Duyne might be a member of another branch of the family, descended from Edward Earle Van Dine, of which “Edward E.” was a common multigenerational given name. It was possible that a member of this completely separate branch had somehow drifted to Morris Co. after 1860 and then, after 1870, had drifted out of the county. Since the other individuals in the record seemed to have no significance, I only copied E.E Van Duyne’s name into my computer record of the census and whenever I browsed the computer record I routinely passed over E.E’s name. Recently, the photocopy of the census page accidentally was exposed on my desk and I noticed the Hopkins entries and on a whim decided to look up Hopkins in my genealogy file. There was a Charles Hopkins in the census record and a Charles Hopkins in the genealogy file and when I compared the two there came upon me that Eureka moment. Charles Hopkins’ wife in the file was Hetty Ann Van Duyne; Hetty A. Hopkins in the census. The other male Hopkins in the census household was John R. Hopkins; in the file John R. Hopkins was Charles Hopkins’ brother. His wife was Elizabeth Ellen Van Duyne: the elusive E.E. Van Duyne. I had found an unusual household where two Hopkins brothers were married to two Van Duyne sisters. The census entry was unusual in that Elizabeth Ellen’s listed family name was Van Duyne rather than her married name of Hopkins. Also, her initials were listed rather than her full name. The written-over gender field was unusual. And the occupation, upon closer scrutiny, became “House Keeping” as opposed to the prior decoding of “House Repair”. Everything fit into place quite neatly and unexpectedly; and I was able to close out another mystery. Charles Ferren Hopkins (1842-1934) and John Robertson Hopkins (1844-1885) were sons of Nathan Hopkins (1811-1889) and Ann Wilson. Hetty Ann Van Duyne (1846-1930) and Elizabeth Ellen Van Duyne (1847-1892) were daughters of Abraham B. Van Duyne (1823-1897) and Caroline Morrison (1824-1903). Carol Hopkins, several years ago, had shared Hopkins genealogies with me which helped, now several years later, to solve this mystery. Dick Van Duyne
