Battle of Castillon
Joel Upton, supporting Waagen's analysis, investigated whether the "famous Talbot" was John Talbot, 1st Earl of Shrewsbury, killed at the Battle of Castillon in 1453. However, John Talbot had only one niece, Ankaret, who died in infancy in 1421. Lorne Campbell suggests that given the Latin signature, Waagen might have misinterpreted the word "nepos", which can also mean "grandchild". Upton concludes that she was more likely a daughter of John Talbot, 2nd Earl of Shrewsbury, either Anne or Margaret. Their parents married between 1444 and 1445, suggesting that the sitter was under 20 at the time of the portrait. She may have travelled to Bruges to attend the famously lavish wedding in 1468 of Margaret of York, sister of Edward IV of England, to Charles the Bold, Duke of Burgundy.
