Dame Elizabeth Yorke

From Two Dozen and More Silkwomen of Fifteenth-Century London by Anne F. Sutton

Affluent and equally capable was Elizabeth Lock, left a widow by the mercer John Lock in 1463; there were six children entrusted to several male custodians so they may not have been hers, but she was appointed one of the executors. It is doubtful that any Lock step-children would have suffered from her second marriage to the stapler William Yorke for it was prudent, wealthy, and had connections to gentry circles.[45]

45. Born a Cokayn, and it is her gentry status which suggests she was Lock’s second ‘trophy’ wife. She had children by Yorke. Lock (d. 1463), PROB 11/5, ff. 7-9; Yorke died 1476 when she was executrix again. She died 1497, PROB 11/11, ff. 113v-14v. Her connections included Thomas Windsor, the nephew-in-law of Alice, last wife of Hugh Wiche, see Sutton, ‘Women of the Mercery’, forthcoming.
