Seymour was born in Carlisle in 1926, the son of William J. Ewing & Jessie Morrison Ewing.  He graduated from Carlisle High School in 1944.  Following graduation he served in the United States Navy during World War II.  After two years of dedication to his country, he returned home to Carlisle.  Seymour's father, William J., died in 1934 leaving Seymour's mother, Jessie, to operate the family funeral home under a widows license.
