The increasing flow of visitors to Loudoun and to Leesburg, its county seat, has developed a steadily growing demand for more information concerning the County's past and its charming old homes than has been available in readily accessible form. These visitors, in their quest, usually call at Leesburg's beautiful Thomas Balch Library which, during Garden Week, lends its facilities to Virginia's Garden Clubs for their Loudoun headquarters; and Miss Rebecca Harrison, its Librarian, has upon occasion found the lack of published information in convenient form somewhat a handicap in her always gracious efforts to welcome and inform our growing tide of visitors. Knowing as she did my lifelong interest in Colonial history and the lives and family stories of the men and women who enacted their parts therein (my sole qualification, if such in charity it may be called, for such a task) she, from time to time, had suggested that I prepare a book upon Loudoun, the people who built up the County and the old homes which they erected and in which they lived. The present volume has been written in an effort to respond to those requests. When some four years ago the work was contemplated, it was proposed to make it primarily a small, informal guidebook to Loudoun's older homes; but as my research into her earlier days progressed, I became deeply conscious that the people of Loudoun have forgotten much of her past that tenaciously and loyally should be remembered; and so the story of the County almost crowded out, beyond expectation, the story of the homes. It is hoped that, sometime in the future, another book pertaining wholly to these old plantations and their owners may be prepared and published. Although there has been no very recent book devoted to her history, Loudoun has had her historians within and without her boundaries and, above all, has been fortunate in attracting the interest of that outstanding scholar and historian of the Northern Neck, the late Fairfax Harrison, Esq., whose beautiful country-seat of Belvoir is near by in the adjoining county of Fauquier. As the most casual reader of the following pages will quickly recognize, I have been under constant obligation, in the preparation of this work, to these earlier writers and can but here sincerely acknowledge the help I have derived from them.
