BLYTHE, BILLY GENE - Funeral services were held this morning (Tuesday) for a Tipp area man killed instantly Friday evening in an auto accident in Dayton.  Billy Gene Blythe, 6930 East U. S. 40, Tipp City, slammed his car into a power line pole in the 900 block of Leo street just before 7 p.m. on July 7.

Survivors include his mother, Mrs. Nettie E. Blythe of Brandt; two sons, Philip and Johnny, both of Dayton; four daughters, Pamela, Nancy, Janey and Melissa, all of Dayton; two sisters, Mrs. Betty Barnett Huff and Mrs. Wilma Farris, both of Dayton; 5 brothers, Jack, Ronald, Michael, David and Daniel Blythe, all of Dayton.  Services were conducted by the Reverend Percy W.
