OCGS has been helping genealogists since 1969. We are a non-profit organization dedicated to helping others with their genealogy research. We work closely with the genealogy department at the Okmulgee Public Library at 218 S. Okmulgee, Okmulgee, OK 74447

Our members share tools, experiences, and knowledge helping you find your family history. We would love your participation, and we welcome new members, even out-of-state. Out of state membership is supported through the use of zoom.
