Wait a minute--- if Fanny Garrison died in 1923 and made this quilt she'd have been way over 100. And wait another minute. Fanny Maria Lloyd Garrison---could she be related to William Lloyd Garrison---that pillar of abolitionist New England?
Her grandchildren (she never knew them) wrote a biography of William Lloyd and included information about Fanny with some of her letters. Those letters survive in several archives.
In 1805 Abijah, Fanny and children moved to Newburyport, Massachusetts, where Abijah hoped they'd be "less expos'd to the Ravages of war and stagnation of business," during the Napoleonic wars that so affected shipping. William Lloyd Garrison was born in December of that year, followed three years later by a sister Elizabeth. Abijah Garrison moved back to New Brunswick soon after but Fanny stayed in Newburyport. A single mother, 32 with two boys and a baby girl, she took up monthly nursing, caring for mothers and infants at birth and afterwards. This assistance at a "lying-in" required she live with her clients for a month or so and her own children were not welcome. Each Garrison went his or her way with another family.
Elizabeth died in August, 1819 after an "illness of three weeks, commencing with bilious fever," a description that could include any kind of infection. Nursing was a dangerous profession and Fanny worried to her son about epidemics in the Southern climate. By the time Elizabeth died in 1819, Fanny herself was not well. Timothy Pickering asked Fanny's help caring for Elizabeth's 9-month-old baby. He complimented her nursing skills, writing that it was a "great satisfaction to know that, in all times of need, [my daughter] had so tender a nurse."
