What are the criteria for those books? Are they complete for a specific period? Also, when did Maryland death certificates include parents' names and birth date of the deceased? I have a Baltimore one with neither; is that true throughout the state to a certain year? I will visit in Oct but want to do everything possible by mail; the visit may be only one day! Looking for death date and place of Benjamin Start, who worked on Dill farm on 1880 census. Thanks, Grace in AK
