I'm looking for any information about my grandparents, Thomas and Margaret Seller, who lived in Harbor Beach at the time my father, Orrin Thomas Seller, was born, July 17, 1902. They would also have had an older daughter, Maude. My grandfather, originally from Ontario, was a grocer and cheese maker; he may have had a grocery store in H.B. at the time. Thank you for any help you can offer.
