Big Sky Genealogy was opened on 16 October 2001 by Sandra & Gary Guynn.  


The store carries a wide variety of books, charts, forms, archival supplies, videos and gift items. For the beginner, there are several how-to books. For those more advanced in researching, there are help guides and other reference materials. There is also a reference library, which can be used by anyone, free of charge. The business also offers research services, book searches, special orders, classes, and speaking engagements.  For a small fee, we will also work with our customers on the Internet; no computer experience necessary.
