We at the Mamaroneck Historical Society have begun the restoration of the historic Florence/Powell Burial Ground located behind Mamaroneck High School. This long neglected cemetery has already been the site of much work over the past year.

All are invited to a rededication of the burial ground.

The final stage of restoration will consist of the restoration of the headstones in the cemetery. Many of the headstones, which date from 1808-1883, are in very poor condition. Some have been toppled or broken over the years...and all are in need of professional restoration.

If you would like to contribute toward the $500 still needed to pay for this restoration, learn more about the campaign and how to donate.

The Mamaroneck Historical Society invites you to join us at the 1816 Schoolhouse to find out!
