The memorials I put on for Stewart Cemetery were found on a paper written by B.F. Fackenthal, Jr in 1910. I found this information at the Spruance Library in Doylestown, PA.
Also I found a paper by Richard A. Plank, dated April 3, 1991, identifying 4 Revolutionary War Veterans buried here.
This is Mr. Fackenthal's note; The Stewart burying-ground to which Mr. Ely refers, known locally as Bunker Hill Cemetery and near which he believes to have been the site of the first Tinicum Presbyterian Church, (of which the church at Red Hill is the successor,) is located in Tinicum Twp. 2 1/4 miles, in a direct line, north-east from Ottsville,and one mile, in a direct line, south-east from Revere. I visited this cemetery during December 1910, and found it badly overgrown with weeds, briers and many saplings. It contains about half an acre; the north and south walls are 120 feet long, and the east and west walls 178 feet long on the outside. It is enclosed by a stone wall 4 1/2 feet high, now partly tumbled down, which originally had a substantial stone coping; the iron gate entrance is still in splendid condition and swings on its hinges very easily. There are evidences of hundreds of graves, many of which are marked with small sandstone markers without inscriptions, but 25 markers with inscriptions could be found, some of these were not in position and some were badly broken. The following is a memorandum of all that remained. These few records show burials as early as 1744, and as late as 1859, but none between 1831 and 1858.
This note, dated 1991, by Mr. Plank reads in part, Tombstones seem to have been removed according to neighbors, sometime in the 1960's or 1970's. There are numerous fieldstone markers with no names on them.
