The David Rowntree family burial ground was located on the farm on Old Weston Road (Lot 35, Concession 3 from the Bay, in York Township.) It includes death dates back to the 1860s. The cemetery was closed and the remains moved to Prospect Cemetery in 1913 where the markers were transcribed for this publication. The booklet includes an introduction and is fully indexed. The index can also be consulted in The Ontario Name Index.
Note that burial records of Prospect Cemetery are available through the Toronto Trust Cemeteries Database on FamilySearch.org.
