Though the headstone or pair of headstones of Quam Tanner and his wife have not been photographed in the cemetery in recent years, the old DAR transcription of headstones in the cemetery would seem to place the Tanners roughly in the NE quadrant of the cemetery around the 38th/39th rows. All the other known graves of African-American veterans are also in the NE quadrant (Civil War veterans Titus Gunn, Jerome Lee, and James Hall along with his wife).
