The following post-em from Curt Hofemann, curt_hofemann@@yahoo.com, puts doubt on her name (at minimum) and probably even her existence. I can't say that I disagree (Marmaer is a title, not usually a name).
I've seen this listed this way all over the internet. Also her gf is listed as "Lord of Mormaer", from Paget. To my knowledge Mormaer was a title not a place. So saying Lord of Mormaer is thus redundant. Also "of" or "de" Mormaer is like saying a king's dau was called (?) of King or (?) de King. (And why the French "de" in Scotland in the 900's?)
It is also doubtful that CrÌn·n's dau would ever be titled Mormaer. If she inherited the honor, which is extremely doubtful considering she had brothers, her husband would have carried the title not her. Whether there was a special title for the wife of a Mormaer (eg; an English earl's wife = countess), I am unaware of what it was.
If you find that I am wrong about this, I would be most grateful should you be so kind as to let me know. Thanks.
