Our library is open for visits from 10 a.m. to 2 p.m. Wednesday – Friday. Visitors must register in advance. We will continue to require masks in our library for both volunteers and visitors for the time being and will reassess this policy in the future. We are also deferring decisions about reconvening in-person meetings and classes and Saturday hours. Thanks for your understanding as we balance the health and safety of our genealogy community. Questions may be sent to [email protected]
