Brian Darwin pulled nine of about 60 granite pavers out of the ground Wednesday night. When he flipped one of the 100-pound slabs over a day later, he was stunned.
An inscription read: "Beloved Wife, Mother Viola T. Bagnasco, 1901-1969."
Caryl Arnet, owner of monument maker Arnet's Inc., said the markers might have been used as a walkway because they contained misspellings or other errors. She said gravestones sometimes aren't picked up after being ordered.
The current homeowner recently moved in. Based on inscriptions, the stones are from the 1960s.
