DuPage County (IL) Genealogical Society

About DuPage County, Illinois

DuPage County, Illinois was formed from Cook County in 1839. With the completion of the Erie Canal, numerous families from Pomfret, CT and other New England towns settled the area in the 1830's and 1840's. The prairie offered rich farmland and the development of the rail system brought settlers from throughout the Eastern states. By 1855, the population stood at about 13,000 people. Agriculture remained the principle economic activity until recent decades during which DuPage County has become urbanized.

Founded in 1974 as the Lombard Suburban Genealogical Society. In May 1981 the Society moved its reference collection to the Wheaton Public Library helping it to become one of the premiere genealogical research locations of the Chicago suburbs. DCGS has continued to contribute to the genealogical collection over the years. In 2003 DCGS obtained the 501(C)(3) registration to enable it to receive tax deductible and matching-gift donations.
