Clyde Poe
11 June 1909 - 15 April 1999 according to SSDI

Parents are Bruce (b. c. 1883 d. 1966) and Jennie (Wible) Poe (b. c. 1890) of Greene, Franklin County, PA. Their children, from various censuses, are:

Albert E. b.c. 1908 d. Apr 1984 SSDI
Clyde E. b.c. 1910
Hazel E. b.c. 1912
Goldie M. b.c. 1913
Viola M. b.c. 1915
Wilber or Wilbert W. b.c. 1919 (may be living in Tampa, FL)
Ruth I. b. c. 1921
Pearle L. b.c. 1923
Glenn b. c. 1926 (may be living in Fayetteville, PA)
Evelyn b.c. 1928
Roy (or Ray) M. b.c. 1929 d. Dec. 28, 2005 SSDI
Clarence b. c. 1932 d. 26 May 1993 SSDI
Isabel b. c. 1933

There is a Glenn R Poe in Fayetteville, PA, which is very close to where this family lived, who has a son Daniel G Poe of Suffolk, VA, according to the obit of his other son, Randy. I cannot verify if this is the right Glenn Poe to be Clyde's brother or not, but he is the most feasible possible relative; if he has passed, his son Daniel would be.
