I am looking for the deaths of my great-grandparents, Robert Kirtley, and Ellen Kirtley. They lived in Stockton-on-Tees, Durham, England. I am also looking for their parents names, and places of birth. I know that Robert was born in Norton around 1854. Their daughter, Annie Marie is my father's mother. She came to the United States at the turn of the century in early 1900's, and married Louis(Lewis) Coryell.
