This person is listed in the record of burials kept by the Rev. Dr. James Muir while he served as the minister of the Presbyterian Church in Alexandria from 1789 until his death in 1820. He did not include the place of burial, but his notations indicate that she may have been buried in the Episcopal burying ground. Church and city historians believe that people on Muir's list who died after 1809, were most likely buried in one of the "new" cemeteries on Hamilton Lane. No grave marker for this person has been found, but her son is buried in the Episcopal Cemetery near the church.
According to Muir, Mrs. Ross died at the age of 60 years; her funeral was held on September 7, 1812. In volume 1, "Tombstone Inscriptions of Alexandria, Virginia," 1992, Wesley Pippenger references probate records concerning Isabella Ross in Alexandria Wills, book 1, page 223.
