Talk:Isabella of Urgell, Duchess of Coimbra

Death date?
The death date listed here is given precisely as 29 August 1443. But it has no citation. An old treatise I've read has her alive down to 1459 - but it is quite an old source (1910), so I'm not sure if that is correct. I'm going to insert it anyway, until a better date is found.
