I have 2 relatives born in Westchester lived in Manhattan and on their death Certificates said burial was in Sing Sing. I'm guessing Dale Cemetery but on find a grave they are not listed. Has anyone out there dealt with Dale Cemetery? I have both dates of death: 1863 Margaret Heleker (found yesterday !!) and 1872 Charles Heleker Would any other cemetery be considered in Sing Sing ? Thank you for your time in advance
