Relationships
(possible) Father: Sir Robert de Holland.
This relationship is given by Ffarington (p. 152) and by Hulton (4:978). Baines (5:74) states that Margaret was a sister of the first Lord Holland, who was Sir Robert’s son. Some authors seem to avoid stating whether Elizabeth’s brother was the the first Lord Holland or his father. (Both were named Sir Robert.) The source seems to be a memorandum in the Whalley Coucher Book (p. 1085) which states that John de Blackburn “...desponsavit Margaretam sororem dñi Roberti de Holand...”, which seemingly could refer to either Robert. If it refers to the elder Robert, then Margaret’s father was Thurstan de Holland. This is what Holland has (chart opposite p. 1).

This relationship is given by Ffarington (p. 152). See above for an alternative suggestion.
