As the great granddaughter of Richard Ratcliffe, the founder of Providence now called Fairfax City, Laura was born there May 28, 1836. When war came she immediately sought to support her family and neighbors. While caring for the wounded she was noticed by Col J. E. B. Stuart for whom she became a valuable spy. There was a large rock near her home where she would conceal money and messages for Col. Mosby. Stuart wrote admiring poems dedicated to her and finally asked her to marry him. Laura, true to her own strong moral convictions, declined. This was near the location of present-day Frying Pan Farm Park. Laura was admired locally for her bravery and her beauty and was acknowledged by Col. Stuart in many ways. He presented her with a gold-embossed brown leather album with the following inscription on the front page: "Presented to Miss Laura Ratcliffe by her soldier-friend as a token of his high appreciation of her patriotism, admiration of her virtues, and pledge of his lasting esteem." The album was signed not only by Stuart but also by many other soldiers who fought with him including Mosby and Brigadier GeneralFitzhugh Lee. Many of her local friends had also signed the book. She quietly kept this memoir, as well as Stuart's gold watch chain, among her possessions at Merrybrook. These items were discovered in her effects after her death. Col. John Mosby, the famous Confederate Ranger harassed Union Army positions throughout this area. Incredibly daring, he rode into Fairfax City one night and snatched Union Brigadier General Edwin Stoughton out of his bed behind Union lines and made off with him. February 7, 1863 - Col. Mosby was planning to raid the Union picket lines in Fairfax when he had word of a band of robbers nearby. These men had been stripping citizen's homes of valuables, stealing horses and even taking the local doctor's medical saddlebags after encountering him on the road. Mosby captured them and sent them to Richmond and returned the stolen property. He proceeded on the next day toward Union picket-post near Frying Pan Church. That night a Union officer, Lt. Palmer of the First Virginia came to Laura's house to ask for some milk. He bragged to Laura that an ambush had been set for Mosby saying, "I know you would give Mosby any information in your possession; but, as you have no horses and the mud is too deep for women folks to walk, you can't tell him; so the next you hear of your 'pet' he will be either dead or our prisoner." He underestimated her. Laura went out on foot across the fields to reach the home of George Coleman to ask him to watch Mosby. As luck would have it, her path crossed Mosby's and she was able to warn him herself, thus saving him from capture. He acknowledged his great debt to her in his memoirs. Ratcliffe's assistance to Mosby, besides saving his life, included providing timely information on Union troop movements, hiding both men and money for him, and occasionally acting as "banker" for the Rangers. Till the end of the War, Laura worked in close cooperation with Mosby. He often used her home as his headquarters, and would meet his men at a large rock outcropping nearby, which was later known as "Mosby's Rock". This was also apparently where Laura successfully hid several thousand dollars entrusted to her after the Rangers had liberated it from a Union train. The Virginia Department of Historic Resources approved a historical highway marker for Mosby's Rock in 2000 denoting its significance.
