Frances Thornhurst

The effects of Mr. Jenyns were administered to May 29, 1668, by Anthony Mildmay, his principal creditor, Frances, his widow, having renounced. She long survived her husband, and on February 12, 1691, 2, made her will (proved January 11, 1693, 4), leaving all her manors, lands, personality, &c., to her daughter Sarah, for her sole and separate use, so that her dear son-in-law, John, Earl of Marlborough, "though I love him from my heart", shall not intermeddle therein, but be wholly debarred," and directing her body to be buried in the Abbey Church of St. Albans, as near as convenient to her "four first children."

She didn't die in Ireland in 1731 at the age of 106.
