looking for a long lost friend

I'm trying to find WILLIAM ( BILLY) P. GILLIS who was from North Hollywood
California, he had two (2) brothers, Bobby and Jerry! We all went to St.
Charles Paroical school on Moorpark Street in North Hollywood Ca.. Billy
went to Loyola High School in Los Angeles Ca. and graduated in 1948.
The last time I saw him was in 1963, he was living in SIMI Valley with his
wife Carol and family and working for AEROSPACE. Billy and I had worked for
RALPH'S grocery store in North Hollywood Ca.. Carol was a cashier at the
same store.
If anybody out there can help me locate Billy or his family I would really
appreciate it! Billy saved my life when I was 14 yrs old!
