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]

Providing additional Online Resources on our website is a priority. These resources include lineage charts developed by our members, which provide finding aids and images. Search to find out if someone you are researching is included.
