The lack of documentary evidence that Hawise Stewart was wife of Sir John de Soules is something that has bothered me for many years. I have just found the entry below in Inquisitions Miscellaneous that should help to resolve this question. It may be that Edward III was seeking to resolve claims to Old Roxburgh by the Lovels.

Best regards,
Jim.

Calendar of Inquisitions Miscellaneous (Chancery), Vol II, 1916. Page 378-9, Item 1547.

"[1547]. Writ to William de Felton, keeper of the castle of Rokesburgh in Scotland, and to the sheriff there. Staunford. 27 June 11 Edward III. [1337]

[Inquisition :— Rokesburgh. 24 July.
Two parts of the town of Old Rokesburgh were given by Sir James, steward of Scotland, in free marriage with lady Hawise his sister to Sir John de Soules, and through her the right descended to Sir James de Lovel as heir ; the third part was given by King John of Scotland to Sir John de Soules, whether for inheritance or only for life the assize is ignorant ; two parts are held of the steward and the third of the king ; in time of peace the town is of the yearly value of 100 marks.

For what it's worth, the referenced patent roll entry reads as follows:

1337.

Sept. 24. Tower of Loudon.

By letters patent of 28 May in the tenth year of his reign, Edward II. granted to Richard Lovel and Muriel, his wife, the manors of Brehull and Silveston to hold until he should grant to them and the heirs of Muriel lands of equal value, in exchange for the manor of Old Rokesburgh of her inheritance, which with their consent he retained for the munition of the castle of Rokesburgh. And afterwards the said Richard and James Lovel, son of him and Muriel and heir of the latter, in the time of the present king entered upon the said manor of Old Rokesburgh and received the issues and profits of all three manors. Wherefore the king summoned the said Richard to speak with him of this contempt, and he, in consideration of the king's right herein, surrendered into his hands the manors of Brehull and Silveston, and afterwards for greater declaration of that right quit claimed all right in them to John de Molyns, to whom the king had granted them by charter, making instant supplication for an indemnity herein. The king, at the instant request of the said John, has pardoned to Richard all the issues of the manors of Brehull and Silveston received by him while the manors were in his hands, has released any action he has or might have against him for waste, and has also released to him and the said James all his right in the manor of Old Rokesburgh.
