I am hoping someone can help with a mystery. I am looking for a death date and possible burial location for Mary Markley Heltzel. Mary was the daughter of David and Marie McFadden Markley. Mary married Alexander Heltzel on May 16, 1882 in Fulton County. She died after 1886 and before 1900, most likely in Fulton County. Both she and her husband were members of the German Baptist Brethren (Dunkard) church. Any help would be appreciated.
