According to Pat Patterson's post to SGM, 23 Feb 2001 (repeated by JohnRavilious 2 Feb 2004), Isolde was married 1stly, before 1250, to Henry dePomeroy/Henry le Pomerai, and 2ndly, between 1260 and 1269, to Roger deBodrugan. I have a later death date (1281) for Henry de Pomeroy, whichindicates that Henry might be the 2nd husband. I also note that PatPatterson estimates the son Henry Bodrugan's birth date as c1263, whichwould certainly indicate a marriage with Roger de Bodrugan between 1260and 1262 (instead of 1269).
I am switching the order of marriages which Pat Patterson stated, andmaking Henry de Pomeroy the 2nd husband, and Roger de Bodrugan the 1st,also adjusting Roger de Bodrugan's death date of 1277 to be "before1265", when Henry de Pomeroy's son was born, and Isolde was alreadymarried to Henry.
