Over the period 1877-1890, Mr. Harris visited all public and church cemeteries, as well as some private or family burial grounds, in the above-named towns of easternmost Long Island, New York that had been in use prior to 1800. The vast majority of the roughly 1,000 inscriptions refer to individuals of English birth or descent, many of whom had emigrated to Long Island from New England. The epitaphs alone ordinarily give the deceased's full name, date of death, and age of death. Many of them also indicate the name(s) and relationships of surviving family members.
