He was born in Altoona, son of the late David and Mary (Romadella) DeLeo. On Aug. 10, 1968, he married Mary Katherine Hill in Morgantown, W.Va.

In addition to his wife, surviving are three children: Joseph DeLeo and wife, Christine, of Hollidaysburg, Victor DeLeo of Boston, Mass., and Dr. Katherine Dangler, MAGD, and husband Colin, of Altoona; and six grandchildren: Bailey, Jordan, Brennan and Paxton DeLeo, and Leo and Nora Dangler.
