Mr. McPherson was interred in the burial ground of St. George's church and a marble slab erected over his grave, which is now secured to the wall of the Mission House, at the west end of the lot on Princess Ann street. On that slab is the following inscription: "Here lies the body of Archibald McPherson, born in the county of Murray, in North Britain, who died August 17, 1754, aged 49 years. He was judicious, a lover of learning, open hearted, generous and sincere. Devout, without ostentation; disdaining to cringe to vice in any station. Friend to good men, an affectionate husband. A heap of dust alone remains of thee, 'Tis all thou art, and all the proud shall be. "Elizabeth, his disconsolate widow, as a testimony of their mutual affection, erected this monument to his memory." COL. JOHN DANDRIDGE. In the burial ground of St. George's church, near the northeast corner of the building, lies buried the father of Martha Washington, which fact has only some years since been brought to light, or if it had been before known, it was by the citizens of the past generation of the town. The reason it was unknown to the present generation is accounted for from the fact that the slab over the grave has been covered with dirt for more than half a century, most likely from the erection of the present church building, and was discovered only a few years ago. When the grave was discovered the slab covering it was cleaned off, and the inscription on it was found to read as follows: "Here lies the body of Col. John Dandridge, of New Kent county, who departed this life the 31st day of August, 1756, aged 56 years." How he came to be buried in Fredericksburg is not positively known. It has been claimed by some persons that he was here on a visit to his daughter Martha, who married Gen. Washington, and the weather was so hot that his body could not be taken back to New Kent county, but that cannot be true because he was buried here more than two years before his daughter married Washington. The most satisfactory explanation of Col. Dandridge's presence in Fredericksburg, that we have heard given, is that he was attending the celebrated races at Chatham, held by Wm. Fitzhugh, which drew to the town people from all sections of the country. But be that as it may, this Col. Dandridge is beyond doubt the father of Martha Washington, unless there were two gentlemen by that name and bearing the same appellation residing in New Kent county at that time, which is not probable. Haydon's "Virginia Families" says of Washington: "Married at White House, New Kent county, Va., Jan. 6, 1759, Martha Dandridge, daughter of Col. John Dandridge, of New Kent county, and widow of Daniel Parke Custis." WM. PAUL--JOHN PAUL JONES.
