The caption for the quilt indicates the curators had little information about Mary Cook Taft.
"According to family history, Mary Malvina Cook Taft made the quilt for her trousseau. She probably made it about 1835, since she was born in 1812 and probably married in her twenties, as was common at the time."
I just happened to be looking for more information about Mary Malvina Cook Taft when I stumbled upon this quilt attributed to her hand. Mary's life is well documented in the published writings of her daughter Julia Taft Bayne and in her husband Horatio Taft's diary in the collection of the Library of Congress.
People in the neighborhood of the Hamptons did not make quilts that looked like this, style the Met curators have noted:
"There is no documentation of where the piece was made, but stylistically it seems most closely related to documented bedcovers from Maryland, Virginia, and South Carolina."
