Gretchen ~ There is no Dorethea or Dorothea Group listed in the Lesley E Voorhees Records for Riverview Cemetery because those records are complete only to 1900. Have you contacted the Riverview Cemetery yet? Cemetery Associations usually have records which include the name of the undertaker. The mortuary's records may include either a copy of the death certificate or something similar that has information on the place and date of death. Since you have the name of the officiant at the funeral and his church, you can write to the First Baptist Church for their records as well. Did "Dorethea" Group actually DIE on March 1, 1906 or was that the date of her burial or the date of her obituary? Hope this helps. Diane Wilson Flynn
