One by one the children left Pine Grove. In 1750 Betty Washington was married to Colonel Fielding Lewis, who built for her the stately house Kenmore, not far from her mother's home, but across the river, on the edge of Fredericksburg. This house is still among the show places of the old town.
In the early days of the Revolution Colonel and Mrs. Lewis tried to persuade Mrs. Washington that she was getting too old to live alone at Pine Grove, and urged her to make her home at Kenmore. At the same time Colonel Lewis offered to take over the management of the plantation. To both entreaties she turned a deaf ear; she said she felt entirely competent to take care of herself, and she would manage her own farm.
However, she consented to make her home in a house purchased for her in Fredericksburg, because "George thought it best." The dutiful son had time to help in the flitting to the new home before he hurried to the North. He was not to see her again for seven long years.
A member of the family described later the days of waiting when Mary Washington directed her household in the preparation of clothes, provisions, and other comforts for the General and his associates: "During the trying years when her son was leading the Continental forces, the mother was watching and praying, following him with anxious eyes," the story is told. "But to the messenger who brought tidings, whether of victory or defeat, she turned a calm face, whatever tremor of feeling it might mask, and to her daughter she said, chiding her for undue excitement, 'The sister of the commanding general should be an example of fortitude and faith.'"
It was November 11, 1781, when the victorious commander next saw Fredericksburg, on his way to Philadelphia from Yorktown. George Washington Parke Custis has described the meeting with his mother:
"She was alone, her aged hands employed in the works of domestic industry, when the good news was announced, and it was told that the victor was awaiting at the threshold. She bade him welcome by a warm embrace, and by the well-remembered and endearing name of George.... She inquired as to his health, for she marked the lines which mighty cares and toils had made in his manly countenance, and she spoke much of old times and old friends, but of his glory not one word."
When the Peace Ball was given in Fredericksburg she was an honored guest. Her son walked with her into the gaily decorated ballroom. She remained for a time, but after a while, from the seat where she had watched the dance, she called him to her side. When she was near she said, "Come, George, it is time for old folks to be at home."
Lafayette visited Fredericksburg in 1784, that he might pay his respects to Mrs. Washington. He found her in her garden, dressed in a short linsey skirt, working among her flowers. After his visit he declared, "I have seen the only Roman matron living at this day."
She still went frequently to her plantation across the river, but as she became more feeble her son gave her a phaeton in which she could cross the ferry in comfort. Her great-granddaughter has written of her appearance when she rolled in the phaeton down the village street:
"In summer she wore a dark straw hat with broad brim and low crown, tied under her chin with black ribbon strings; but in winter a warm hood was substituted, and she was wrapped in the purple cloth cloak lined with silk shang (a present from her son George) that is described in the bequests of her will. In her hand she carried her gold-headed cane, which feeble health now rendered necessary as a support."
