•
Richarda of the Marck, wife of Bernard V, Lord of Lippe who, upon his death before 1365, gave his lands to first Otto VI of Tecklenburg, then to Simon III, Lord of Lippe, starting a decades-long feud
His mother was Richarda Croke (1743?-1812), sister of Sir Alexander Croke, of Studley Priory, Oxfordshire.
In the ancestral lands around the cities of Lippstadt and Rheda, however, the situation was complicated, because after the death of his uncle Bernard V, around 1365, his widow Richarda had initially given his part of Lippe to Count Otto VI of Tecklenburg, who was the husband of her eldest daughter.
Reiby was born in Hadspen, Van Diemen's Land, (now Tasmania) the son of Thomas Haydock Reibey and Richarda Allen, and a grandson of Mary Reibey.
