Hi Carol, I looked into David Calhoun and it looks like his wife died before 1900 because I found David with his daughters Margaret and Victoria A. living in San Francisco, CA in 1900.
Both daughters died well before 1885 so it couldn't have been either one of them.

Remains are not supposed to be moved without a burial transit permit which states where they are being moved to. I'd talk to the cemetery and ask to see the transit permit. It's very upsetting that someone can walk in, claim to be a family member and move the remains. Hopefully this is of some help.
