Harvard Divinity School Library is the official repository for the Unitarian Universalist Association amd our collections are particularly strong in the Unitarian Universalist (UU) tradition.
HOLLIS, our library catalog, is a good place to begin exploring Unitarian Universalist congregational records. Search the congregation's name, and also more general keywords, e.g. Universalist and Cambridge.
If you know the name of the minister who served while yoour ancestor belonged to the church, search the minister's name in HOLLIS. If you do not know the minister's name, you may find it in a Unitarian, Universalist, or Unitarian Universalist yearbook.
