Martha Daniell was born in St. Thomas Parish, South Carolina, on December 29, 1704, to Martha Wainwright and Robert Daniell, a deputy-governor. Robert Daniell died in the spring of 1718, and Martha married George Logan, Jr., on July 30, 1719; she was fourteen years old. Rather than confining her talents to traditional domestic duties, Daniell Logan recast the domestic arena as a place of business. She ran a boarding house and school in Wando River, South Carolina, on land she had inherited from her father and where she and George had settled after their marriage. Daniell Logan gave birth to eight children, six of whom lived to adulthood. Not only did she run the plantation and boarding school at Wando River, but she also established a boarding school in Charleston after the family moved to that city, and she acted as an attorney for one of her sons in the sale of properties he owned.
Daniell Logan's greatest talents were as a horticulturalist. By 1753 she was placing advertisements in the South Carolina Gazette, noting that seeds and roots were available for sale at her home. She corresponded with other botanists, such as John Bartram, and published a "Gardners Kalendar" as early as 1752; it was reprinted several times in various almanacs, the last printing occurring in the 1780s. In 1796, after her death, the most extensive version of her "Gardners Kalendar," and her first signed writing, was published in The Palladium of Knowledge and was repeated in issues through 1804. She not only cultivated her own extensive gardens, which supplied other botanists with samples, but she also gathered her roots and seeds from various neighbors' property as well as her own--she mentions Mrs. Bee, Mr. Raper, Mr. Glen, and Mrs. Hopton, among others, as contributors to her naturalist studies.____________________
