Biographical / Historical Note: Thomas E. Dater (1929-2013) was a publisher and a Ramsey-based businessman and historian. Adopted as an infant, Thomas Dater joined a family with historic roots in Ramsey and an interest in genealogy. His grandfather John Y. Dater, II, founded the Ramsey Journal in 1892, and both he and his father, John Y. Dater, III ran the paper. Thomas Dater renamed it The Home and Store News. Joan Lutz Dater (1942-2016) a journalist and educator, met Thomas Dater when she worked a part-time job at the Ramsey Journal. They married in 1964 and had two children, Gretchen (1968-1988) and Christopher (1973- ). Gretchen Dater’s death in the terrorist attack on Pan Am Flight 103 over Lockerbie Scotland was a terrific blow to the family and both Thomas and Joan and they became deeply involved in the Victims of Pan Am Flight 103 and anti-terrorism activities. Both Daters were interested in history and participated in many philanthropic activities.
Collection Description: Mostly genealogical and historical documents focused on Mahwah-based families. Materials on the Havemeyer family include a financial ledger which documents investments, and other financial records; legal records of New York banker William Butler Duncan (1853-1912), acting on behalf of the Havemeyer family. Marie Havemeyer Godfrey’s wills from 1908 and 1923. Henry Havemeyer appointment of Charlotte Havemeyer as his attorney and a birth certificate for the daughter of Marie Havemeyer Tiffany and Perry Tiffany. There are also newspaper clippings, and contracts regarding Mountain Side Farm, McKee Brothers, and Charlotte Havemeyer for work done on the property in the 1950s.
The Hagerman family records include photocopies of the wills of Henry B. Hagerman, Andrew H. Hagerman, Emily A. Hagerman, and copies of death certificates and other records.
Of particular interest are records from the New York City-based Riot Relief Fund founded following the New York City Draft Riots. The organization, which still exists, shifted its focus from supporting the families of those who quelled the riots to providing relief to the families of New York City police and firemen. These records, from 1930 include correspondence and financial records documenting payments. William Butler Duncan was the president of the Fund at that time.
Records about the World War I service of Henry Godfrey, the husband of Marie Havemeyer Godfrey.
