A Note About Family History Research

The Mary Baker Eddy Library is not a genealogical library. However, we can respond to some queries using organizational records of the Church of Christ, Scientist, including membership records for individuals who passed away before 1974. Member records typically include only the following information: name; date of admission to membership in The Mother Church, The First Church of Christ, Scientist; mailing address at time of admission; and, date of decease or withdrawal from membership.  Additional information on members who were practitioners listed in The Christian Science Journal includes dates of Journal-listing.  Please note that member records do not include baptismal, marriage, or other family history information. Contact Research and Reference Services for more information.
