Connecting people to their diverse family heritage

Our library is open for visits from 10 a.m. to 2 p.m. Wednesday – Friday. All visitors must register in advance.  However, CGS members may visit on Friday without registering, as part of a new trial program. We require masks in our library for everyone, and our COVID-19 Mitigation remains in place. We are not yet holding in-person classes or Saturday hours. Questions may be sent to [email protected]org. See our Classes and Events  for online sessions. See a video tour of our website and library.
