I found the contact information for the members of the Hamden Plains Cemetery Committee; however, I don't know if they're paid employees or volunteers, so I won't list their contact information here.

To find their contact information, go to Hamden.com and search for "Hamden Plains Cemetery". Then, open one of their documents and you can see the names of the committee members.

Then, you can simply Google their names and find their phone numbers.

I hope this information helps.
