Edmund de Lacy 2nd Earl of Lincoln
Another name for Edmund was Edmund de Lacie 2nd Earl of Lincoln.
Commonly called the "second Earl of Lincoln," although he died before his mother and therefore did not actually inherit the title.
From Magna Charta Barons, pp. 102-103:
Edmund de Lacie, second Earl of Lincoln, d. 1257. He is called the second Earl, although the title was never attributed to him in any charter, by reason that he died before his mother, through whom the dignity came. Dugdale states that he married, in 1247, 'an outlandish lady from the parts of Savoy, brought over purposely for him by Peter de Savoy, uncle to the queen, which occasioned much discontent amongst the nobles of England.' This lady was Alice, daughter of the Marquess of Saluces, in Italy, and a cousin of the queen."
