I am searching for information on John L. Durling and his wife Mary (?), they were both born in Nova Scotia about 1842. They are listed on the 1880 US Federal Census for Boston, Ma. along with their children Lizzie, Charles, and Harry.They had a boarder Harriet Tupper living with them who was also from Nova Scotia.The three children were all born in Massachusetts. Any help would be appreciated. Thanks.
