The following is a post by Linda (lindas4@@aol.com) to soc.genealogy.medieval concerning Aline's first marriage (and apparent divorce) to John Marshal.
Thank you for all the references! After reading your note, I found an interesting writeup regarding Aline's first marriage. Citing a piece by Painter called "William Marshal, Knight Errant, Baron, and Regent of England", the author notes that John FitzGilbert Marshall, first husband of Aline Picard "willingly gave up his wife to make peace with the Earl of Salisbury". Given that John married Sybil de Salisbury in 1146, I guess that was the method he used to cement his new friendship with the earl.
Based on the date of John's second marriage, I assume Aline remarried (Stephen Gay) in the same year, or afterwards. This does make me wonder about the birthdate I have for Aline de Gai. It would seem that her father, Philip, would have to have been born in 1147 or later, and every birthdate I have seen for daughter Aline is between 1154 and 1160. Unless these folks were very precocious, it would seem that there is a date off here somewhere.
Note: in terms of the dates, I have a slightly earlier marriage (1142 .vs. 1146) date for John & Sybil; apparently the divorce was "by 1141", on the grounds of consanguinity (too close of kinship, the closeness required for grounds ranged between 4th cousins and 14th cousins depending on the period), which was a common excuse for such divorces, so that John could marry Sybil, according to another posting to soc.genealogy.medieval by Richard Borthwick on 21 June 1999.
