I suspected Martin B had a brother by the name of Thomas Morris who married sisters Matilda Zeigler and Alice Eugenia. My nephew came across a picture of Thomas and Matilda, but I couldn't match them to anyone in my line. And, I can't find a Thomas Morris that was a sibling of Martin B Coates. The only siblings of Martin B Coates that I've found are Morris T, Paul L, and Christerfield Coates. If you have sources showing Thomas Morris Coates being a brother of Martin B Coates, then could you tell me where to look? I sure would appreciate that. Martin B and Alice Eugenia (Ziegler) Coates are my maternal grandmother's parents. (My mother's middle name is Eugenia after Alice Eugenia. I'm Michael Behrens, grandson of Dorothy Loretta Coates LaVigne. My tree is "Michael Behrens Family Tree".) Anyway, I can't find anything on the death dates of Martin B and Alice E. I do know who Martin's parents are: Martin Morris Coates (from Yorkshire, England) and Colasta Gordon. I haven't been able to find any death dates on Martin B Coates or Alice Eugenia Ziegler.
