> Father Hay claimed Sir William Sinclair, the founder of the Sinclair family, was French and son of Robert de Saint Clair and Eleanor de Dreux, daughter of Robert II de Dreux. How much credence can be given to this claim? The marriage between Robert de Saint Clair and Eleanor de Dreux is well document but was Sir William Sinclair really their son? An argument against it at
https://www.wikitree.com/wiki/St_Clair-21 is that was a Scottish Henry de St-Clair who could have been William's father.
Father Hay did not claim that Sir William St. Clair of Rosslyn was the son of Robert de St. Clair and Eleanor de Dreux. He only observed that he found an entry for Robert de St. Clair in the history of the house of Dreux. Father Richard Augustine Hay, Genealogie of the Sainteclaires of Rosslyn, 2002 edition, James Maidment ed., and Brother Robert L.D. Cooper, ed. (Edinburgh: Grand Lodge of Scotland, 2002), p. 34. There is a more recent book on the St. Clairs in Scotland that also looked at primary source documents in which the authors show that William St. Clair of Rosslyn was not the son of Robert and St. Clair and Eleanor de Dreux. Gerald Sinclair and Rondo BB Me, The Enigmatic Sinclairs: The Definitive Guide to the Sinclairs in Scotland, Volume 1 (McMinnville: St. Clair Publications, 2015), p. 224-227. There is some question as to whether William St. Clair of Rosslyn descended from the St. Clairs of Hermandston. Enigmatic Sinclairs, p. 177, 185, 192, 199. In 1162-1190 Richard de Moreville, son of Hugh I de Moreville, gave Herdmanston to Henry de Sancto Claro. Enigmatic Sinclairs, p. 157-169;

Alan de Sancto Claro, son of Henry de Sancto Claro of Herdmanston married Mathilde de Windsor., with her maritagium funded by William de Moreville.
www.poms.ac.uk/record/source/2716/ citing K. Stringer, “Acts of Lordship: the records of the lords of Galloway to 1234,” T Brotherstone and D. Ditchburn, eds., Freedom and Authority, Scotland c. 1050 - c. 1650 (East Linton: Tuckwell Press, 1996), p. 223; see also Hay, Genealogie, p. 35. K. Stringer may have suggested that Matilda was the daughter of Alexander de Windsor and Agnes, daughter of William I de Lancaster. Enigmatic Sinclairs, p. 173-174. That would explain why William de Moreville, cousin to Agnes de Lancaster, funded Mathilda's maritagium.
Can anyone help with Matilda de Windsor, such as any other notice of her? I cannot see where she participated in the inheritance from her brother, Alexander II de Windsor of Cumbria and Berkshire with her possible sister, Christiana de Windsor, wife of Duncan de Lasceles and her other possible sister, wife of Hugh de Hosdenc and mother of Ralph de Hosdeng. In 1200, Duncan de Lasceles and wife, Christiana, offered 10£ to have the land of Boulton in Cumberland that was Christiana’s inheritance from her father since she could not have her reasonable part of the inheritance in Scotland. In the year 1202, Christiana de Wyndleshore granted land in Patestun [Paxton] Scotland adjacent the land of Hugh de Hodene to the Priory of Lanercost for the souls of William the King [of Scotland], of her husband, her children and Walter de Wyndleshore, her brother. In 1203, Christiana de Windlesor gave 200 marks that she would be recognized as heir of her brother, Walter de Windlesor and have seisin of his lands in Essex and Hertfordshire and Yorkshire. In 1206, Ralph de Hosdeng and Duncan de Laceles and wife, Christiana, offered 40 marks in Bedfordshire for the total land of Walter de Windlesor held in capite. After 1203, Ralph de Haudeng granted land in Bekenesfeld [Beaconsfield, Buckinghamshire] that had been given by Lord Walter de Wyndlesore, his avunculus [here, uncle]. In 1209, Duncan de Lacelles and wife, Christiana entered a fine with the Abbot of Geddesworthe for the advowson of Bastorethwait [Bassenthwaite in Cumbria]. In 1210-1212, Ralf de Hodenges held 3 1/3 knights’ fees of the barony of Walter de Wyndersores in Buckinghamshire. In 1211-1212, William Briwere accounted for the marriage of Christiana, daughter of Duncan de Lasceles, with ½ the vill of Burneham, Buckinghamshire, and debts of Walter de Windlesores.
