"In about 1841 John W. Brown married Sarah Ann Miller, and their children were; Brittania, who married Alfred Forman and later married Addison Slamm; Ambrose, Oliver, Andrew, Dollie who married F.A. Tschiffely, Calvin, Almira who married Samuel G. Mulloy, Waite and Olivia. The only surviving children now are Mrs. Tschiffely and Mrs. Mulloy. In the family cemetery situated about a quarter of a mile from the house near the electric car line will be found, among others, tombs of the following; John W. Brown, born April 22, 1799, died June 28, 1862; Sarah Ann Brown, wife of J.W. Brown, born June 14, 1823; Elizabeth Olivia Brown, born February 17, 1859, died September 7, 1862; Calvin M. Brown, born April 21, 1851, died December 22, 1887 John Miller died March 9, 1842; Sarah Miller, died April 23, 1860. (The last two mentioned parties being the father and mother of Sarah Ann Brown, wife of J.W.B.) There will also be found in the cemetery tombs of quite a few other Millers. There were also two other cemeteries where the slaves were buried. One was located near the slave quarters about two hundred yards north of the White House near where the old house now stands in the field. No trace of this cemetery is found at the present time. The other is located about three hundred yards north of the family burying ground, whore the big sassafras tree stood and I believe is still standing, and there will be found rough stones-marking the graves."

John W. Brown and Sarah Ann Miller were associated with the historic "White House Tavern", built by John Brown in 1834, previously "Rhodes Tavern", later the "Del Haven--White House Motel". All stage coaches between Baltimore-D.C. stopped there, also cattle drives with up to 500 head of cattle. There were 52 slaves, twenty out-buildings, milk house, smoke house, barns, stables, granary and meat house, slave quarters north of the hotel, a spring, a nearby mill "Brown's Mill" and electric car line. George Washington recorded in his journal that he 'Dined at Rhodes' December 18, 1798 on his last journey from the capitol in Philadelphia to Mount Vernon. [3], aka "Brown's Tavern", there was a historical stone mile marker "25 M to B" (25 miles to Baltimore) (photos)[4][5]
