In normal times, Membership Meetings on a topic of local historical interest are held at 7:00 PM the second Tuesday of every month, with the exception of December.  Meetings are held at the Cornerstone Genealogical Society Library in the adjoining Old Log Courthouse, unless otherwise indicated.  These meetings are open to the public and are expected to resume in 2022.  Zack Patton is our Program Director.
