Sources to consider for Pre-1500 Sir Reginald Crawford

Question

Good evening,

I've located some sources that may help strengthen the profile for Sir Reginald. If those with the pre-1500 certification can review carefully --  the Comments section mentions this profile is frequently confused with another Reginald Crawford.
 

• "ii. Sir Reginald de Crawford, who married the heiress of Loudoun,* by whom he left two sons: L Hugh, who succeeded him in Loudoun;"
• "iv. Sir Reginald de Crawford, succeeded to the remaining half of Crawford-John. He was a steady adherent to Robert Bruce— from whom he got the lands of Crumshuc (Crumock ?) in Cunninghame, that had belonged to John Balliol. He was succeeded by his son, y. Roger de Crawford. He was taken prisoner at the battle of Durham in 1346."

• "The first person, so far as known, who used tlie surname of Crawford, was Sir Galfride de Crawford, in the time of Malcolm IV. and William the Lion. He witnesses several deeds of King William to the Abbey of Arbroath, and he seems to have been in some way attached to the Court of that Monarch. Sir John de Crawford, Knight, and Sir Reginald de Crawford, Sheriff of Ayr, in the reigu of Alexander II., appear to have been brothers, and very probably were sons of Sir Galfride. Sir John was proprietor of the barony of Crawford in Lanarkshire, and the Chronicle of Melrose states that he died in 1248. He left two co-heiresses. The elder of them was married to Sir Archibald de Douglas, Lord of the same, and the younger to William de Lindsay, Knight, Lord of Crawford."

• "Contemporary with the above Galfridus de Crawford was Gualterus de Crawford, witness to a charter of Roger, bishop of St. Andrews, sometime between 1189 and 1202. From him came Sir Reginald de Crawford, who, about 1200, mar- ried Margaret de Loudoun, the heiress of the extensive barony of Loudoun in Ayrshire. He was the first vice-comes or high sheriff of the county of Ayr, an office hereditary in his family. In consequence of this marriage he quartered the arms of Loudoun with his own."
