Here it is! This is the Daly marker seen in the funeral scene of "The Godfather" standing strong today as it has since the early 1880s.

With this photo I am proud to raise the Daly family up from the obscurity of their grave and give them their rightful credit as extras in "The Godfather." :-D The tombstone reads:

ERECTED BY THE CHILDREN IN MEMORY OF THEIR BELOVED PARENTS
THOMAS DALY, DIED FEB 13 1887 AGED 80 YEARS
BRIDGET DALY, DIED MAY 6 1880 AGED 66 YEARS
ALSO THEIR BELOVED BROTHER
JOSEPH DALY, DIED JAN 30 1880 AGED 45 YEARS

The area behind this marker is where Al Pacino and the others sat. This marker has a lot of unmarked graves behind it, leaving lots of unimpeded ground for the cast and film crew to set up shop.
