Membership is open to anyone who believes in these purposes. The location rotates among the eastern, central, and western parts of the United States. The officers are a president, vice president, Journal editor, and membership services coordinator. Every other year the members attending the annual meeting elect a vice president for a two-year term, after which that person serves as president for two years. The membership services coordinator and Journal editor are appointed by the other officers for an indefinite term to give continuity to the organization.
Officers serve on a voluntary basis.
The management of the affairs of the Fellowship is entrusted to these four officers, except that the members must vote upon any change in the amount of dues or any major change in policy. Members are encouraged to donate family genealogies or other genealogical resources, published or unpublished, to the Fellowship. These are reviewed in Brethren Roots and then are added to the holdings of BHLA, where they are available to researchers. Each year at the Church of the Brethren Annual Conference an exhibit booth is maintained throughout the Conference on behalf of the Fellowship. The officers invite the help of members in staffing the booth.
