Whether you're new to researching your family history or have been researching since actual letter writing was involved, we are here to help!
The Sioux Valley Genealogical Society is a group of volunteers dedicated to collecting, preserving, and sharing information about families, past and present, who have ties to the Sioux River Valley region in South Dakota, Iowa, Minnesota, and Nebraska. Founded in 1972, we are a 501(c)3 nonprofit organization that provides resources, educational programs, and events for people who are interested in pursuing genealogical research and preserving their family history.
Our Mission:
- To give assistance to individuals and organizations interested in genealogical research through a local association focused on genealogy.
- To preserve and collect genealogical and historical records and information in a research library.
- To educate members on current genealogical topics through meetings, workshops, and publications.
