A necrology service is a type of service that memorializes the lives of multiple people or animals. The definition of necrology is a list of deaths or an obituary.
Churches sometimes hold necrology services for pets of their members as part of a "blessing of the animals" service. The Lions, Rotary International and fraternal organizations frequently hold necrology services as part of their annual conventions to honor the memory of members who died during the year. The names of members are read along with mention of their contributions to the organization. Historical necrologies can be important sources of ancestral information.
