Talk:Jorge de Lencastre, Duke of Coimbra

Lencastre?
Lancaster? Why? — Llywelyn II   04:42, 24 December 2017 (UTC)

- Perhaps he needed a surname that did not claim any Iberian throne but provided rank, and used that of his double great-great-grandmother Philippa of Lancaster? 14:28, 29 April 2021 (UTC)

Indeed, Philippa seems to be the reference point here. The article in the portuguese Wikipedia states (concerning the spelling): Essa descendência vem usando o apelido sob a forma original Lancastre, mais perto do inglês, e não Lencastre, como depois também foi conhecido este sobrenome, oriundo da rainha Filipa de Lancastre (Lancaster), mulher de João I., meaning that Jorges offspring spelled themselves "Lancastre" instead of "Lencastre" and that Lancastre was chosen after Philippa, wife of John I of Portugal. --Proofreader (talk) 15:03, 11 October 2021 (UTC)
