The information which provides the erroneous parentage is widespread throughout the Genealogy web sites, which of course does not make it correct.
Regrettably, there is a lot of disinformation on the worldwide web.
Yes, the information concerning parentage is clearly incorrect but one of the individuals is probably correct.
More likely to be Sir Malcolm's, I would have thought.
The names Agathe Ogilvie and Agathe Ramsay appear interchangeable and data is more or less the same throughout.
I still wouldn't trust it. I suspect a lack of understanding of the fact that a married woman in Scotland legally retains her maiden surname, and until the 18th century married women are normally referred to by their maiden name, but sometimes as "xxx yyy
or zzz" where xxx is their given name, yyy is their given name and zzz is their husband's surname. This form is still used in Scottish legal documents.
The Ogilvy connection also appears within the Ramsay data and Margory Ogilvie is Agathe's grandmother.
I don't doubt that there were plenty of Ogilv*/Ramsay marriages.
As a matter of curiosity, what exactly are these dubious 'sources'? If any of them are in any way correct, they should say where the information came from, so that you can follow it back to a primary source (original contemporary document).
PS I am greatly diverted by one statement online, that "A ram in the sea is said to have been an emblem on the seal of Ramsay Abbey in Huntingdon in the 11th century." As the language of the upper echelons of society in 11th century England was Norman French, the idea that an abbey well inland away from the sea should have an obviously Anglo-Saxon explanation for such a seal strikes me as rather fanciful!

The Surnames of Scotland says, "
The Ramsays are supposed to have come from Huntingdonshire where Ramsey is a local name (Latin de Rameseia)". I
speculate that the 'ey' element of the name is probably more likely to be from a Norse word for 'island', and that the abbey was built on an island of firm ground in otherwise wet low-lying land, like Ely not so far away. But I may well be entirely wrong about that.
