I am in search of any information regarding my half brother Marine PFC Edward John Taggart. Edward was in Company I, 3rd Brigade, 5th Marines, 1st Marine Division. He was born 22 Feb 1933 in Hannibal, New York and was killed in action Jul 21, 1952 in Korea. He is buried in Bozeman, Montana. He had enlisted on May 17, 1951. The Military Personnel Records Center in St. Louis will not give me any info regarding him because I am not directly related to him. I am also looking for his sister Bernice born in 1935 who should still be living. Both may have been members of the Seventh-Day-Adventist church. Any help will be much appreciated. Thanks in advance.
