Aug. 18, 1799 Boston Suffolk County Massachusetts, USA
From the files of Waldo Sprague "Children of D.(I believed this is actually M for Mildred) Bates. Daniel Jr a graduate of Harvard (university) died in Boston Aug. 18, 1799 age 20 & interred in Central Cemetery."
I am including Daniel in this cemetery as this is where his memorial is. I don't have any other info other than Waldo's files to confirm his actual place of burial.
