Madach, 1st Earl of Atholl - Unsourced extra children

Can you quote the sections for them?

Hang on: Found one

"31. kafli Auðun átti Mýrúnu, dóttur Maddaðar Írakonungs." Landnámabók
https://www.snerpa.is/net/snorri/landnama.htm

Chapter 31 Auðun married Mýrúna, daughter of Maddad the King of Ireland.

No Margaret in Landnámabók

or in Eyrbyggja saga that I can find?

Douglas John Nimmo can you find it for us for your profile?

Okay, so step by step:

1. On Geni, your profile for her [[Myrun Maddaðardóttur Bjadmakdotter Myrun Maddaðardóttur Bjadmakdotter] is definitely placed as the daughter of Madach, 1st Earl of Atholl not Bjaðmak (Beadh-mac ( Maddad). [[Bjadmak, King in Ireland Bjadmak, King in Ireland] So, this is the one we're looking at. (Although both seem - rather too coincidentally? - to have been married to an Audun, and both have a father whose name is Maddad - cf Myrun Maddaðardóttur Bjadmakdotter ]

2. Problem: The Earl of Atholl is Scots, not Irish

3. Problem: The Irish don't seem to know about Bjadmak, King in Ireland or Beadh-mac as one of their kings / nobles. Is it a reference to Macbeth, King of Scots ?

4. Problem: Macbeth isn't Irish either, and his dates are way past 890

5 RE mýrúna and margrethe as same person. What evidence that the names are interchangeable? Caithness certainly isn't interchangeable with Atholl, and, again - neither are in Ireland.

Okay, let me know how/where I can help.

Disconnecting the relationship to Margaret de Caithness pending the provision of sources to use to reconnect.
