I am researching a Henry Hartman family who had lived in Seward Co. NE. His daughter Emma is my husband's gr. grandmother. Henry was married to Theresa Zirot, both being born in Prussia. I am trying to establish any relationship to the many Hartmans who lived in the area 1880's. I know very little about this family. I do have a portrait of Henry and his wife. Any help would be greatly appreciated. Emma was born in November of 1885, and had sisters Martha, Ida, maybe Clara and maybe Bertha.
