James H. SHEEHAN, Chatham (North. Co.) N.B. arrived in this city Tuesday night in search of a long lost sister. It has been many years since he has seen her, but his zeal in searching the U.S. for her has thus far been in vain. After searching for eight years he accidentally learned that she was in Portland as a housekeeper in a private family. She left Chatham 8 or 9 years ago. Her real name is Ellen SHEEHAN and she is 41 years of age. - Portland, Me. Press.
