About Mael Muire mac Donnchad, Mormaer of Atholl
Máel Muire of Atholl was Mormaer of Atholl at the beginning of the 12th century, until sometime perhaps in the 1130s. According to the Orkneyinga Saga, Máel Muire was a son of king Donnchad I and a younger brother of King Máel Coluim III.
Son of Duncan and Sibylla/Suthen.
Father of Moddan.
A Malmori d' Athótla is mentioned in a charter relating to a year after 1130, contained within the Book of Deer. If the first part is true, and the second part refers to the same Máel Muire, then this Máel Muire lived for more than 90 years, between the death of King Donnchad I in 1040 and the 1130s. It seems likely that his paternal grandfather Crínán was also Mormaer of Atholl. Máel Muire then probably inherited the Mormaerdom in compensation for not inheriting the Kingship.

Máel Muire, Earl of Atholl is a possible third son of Duncan I King of Scotland, although this is uncertain.
DUNCAN King DUNCAN I 1034-1040; [Donnchad], son of CRINAN "the Thane" Mormaer of Atholl & his wife Bethoc of the Scots (-killed in battle either Bothganowan/Pitgaveny, near Elgin, or Burghead 14 Aug 1040, buried Isle of Iona).
m () SUTHEN [SIBYLLA], [cousin of SIWARD Earl of Northumbria, daughter of ---]. The Chronicle of John of Fordun records that the mother of Malcolm and Donald Bane, Duncan´s sons, was "the cousin of Earl Siward". This information is not included in any earlier source and should be considered dubious. In one earlier king list, King Malcolm III's mother is named "Suthen". No reference has been found in primary sources to her being named Sibylla, the name found in many secondary sources. Cawley’s Medlands
King Duncan I & his wife had [three] children:
1. MALCOLM (1031-killed in battle near Alnwick, Northumberland 13 Nov 1093, buried Tynemouth, later transferred to Dunfermline Abbey, Fife, and later still to Escorial, Madrid).
2. DONALD (- died in prison Rescobie, Forfarshire 1099, buried Dunkeld Abbey, later transferred to Isle of Iona).
3. MAELMUIRE [Melmare] (-died after ). According to the Complete Peerage, Melmare, who it says was the father of Madach Earl of Atholl, was the son of Duncan I King of Scotland & his wife ---, but it cites no corresponding primary source. The primary source which confirms that this is correct has not yet been identified. The only primary source reference to Maelmuire which has so far been found is the undated charter under which David I King of Scotland granted protection to the clerics of Deer, which is witnessed by "Donchado comite de Fib et Malmori d´Athotla et Ggillebrite comite d´Engus et Ghgillcomded Mac Aed…". From the names of the earls of Fife and Angus, it is unlikely that this document can be dated to before 1135 at the earliest. If that is correct, it is evidently impossible from a chronological point of view that Maelmuire could have been the son of King Duncan I.] Cawley’s Medlands
