Ragnall mac Somhairle, Lord of the Isles - MacDonald Clan Descent line

Assuming that it is correct that the MacDonalds descend from a Donald Grandson of Somerled - this is the descent line template for that Donald - taken from Medlands:

[Ragnall mac Somhairle, Lord of the Isles REGINALD], son of SOMERLED Lord of Argyll & his wife --- of Man (-after 1192). The Chronicon Manniæ et Insularum names “Dulgallum, Reginaldum, Engus et Olavum” as the four sons of “Sumerledo regulo Herergaildel” and his wife the daughter of Olav King of Man[1355]. Balfour Paul states that Reginald inherited "Kintyre and Isla" but drove his brother Angus out of Bute and Arran, but does not cite the corresponding primary source[1356]. Lord of the Isles. "Reginaldus filius Sumerled dominus de Inchegal…et uxor mea Fonie" donated cows and other revenue to Paisley monastery by undated charter[1357]. Balfour Paul dates this charter to [1180], although he does not state the basis for this speculation[1358]. The Chronicon Manniæ et Insularum records that Engus, son of Somerled, defeated his brother Reginald in 1192[1359]. The Book of Clanranald records the death of Reginald in 1207[1360].
m [Fionnghuala of Moray, Lady of the Isles FONIE], daughter of ---. "Reginaldus filius Sumerled dominus de Inchegal…et uxor mea Fonie" donated cows and other revenue to Paisley monastery by undated charter[1361].
Reginald & his wife had [three] children:
>*1. [Donald, Lord of the Isles DONALD] (-Island of Kerrara 1249, bur Iona). He succeeded his father as Lord of the Isles. "Douenaldus filius Reginaldi filii Sumerled…et uxor mea" confirmed his father’s donation of cows and other revenue to Paisley monastery by undated charter[1362]. The Annals of Ulster record that "the sons of Raghnall, son of Somurlech” fought "the men of Sciadh" [Skye] in 1209 "wherein slaughter was inflicted on them"[1363]. The Chronicle of John of Fordun records that King Alexander II led an army into Argyll, dated to 1221 from the context, and subdued the land[1364]. Balfour Paul states that Donald died "in the island of Kerrara in 1349" and was buried "in Iona", but he does not cite the corresponding primary source[1365]. m [NN Stewart ---] Stewart, daughter of [Walter Stewart, 3rd High Steward of Scotland WALTER FitzAlan Stewart High Steward of Scotland] & his wife ---. Balfour Paul states that Donald married "a daughter of Walter High Steward of Scotland", but he does not cite the corresponding primary source[1366]. Donald & his wife had [three] children:
>>*a) [Aonghas Mor mac Domhnaill, Lord of Islay ANGUS Macdonald] (-[1296]). He succeeded his father as Lord of the Isles. A charter dated 1292 records safe conduct granted to "Anegus filius Dovenaldi et Alexander filius eius"[1367]. "Angus filius Douenaldi" donated revenue to Paisley monastery by undated charter, witnessed by "Alexandro fratre meo…"[1368]. Balfour Paul says that the Lord of the Isles became the vassal of the Scottish king under the terms of the treaty with Magnus IV King of Norway in 1266[1369]. m [NN Nic Colin Campbell, of Lochawe --- Campbell], daughter of [Sir Colin Mor Campbell, Chief of Clan Campbell COLIN Campbell of Lochow] & his wife ---. Balfour Paul says that Angus married "a daughter of Sir Colin Campbell of Lochow" but does not cite the corresponding primary source[1370]. Angus & his wife had three children:
>>>*i) [Alexander Og MacDonald, Lord of the Isles ALEXANDER Macdonald] (-after 1308). A charter dated 1292 records safe conduct granted to "Anegus filius Dovenaldi et Alexander filius eius"[1371]. He succeeded his father as Lord of the Isles. He opposed Robert Bruce and was appointed Admiral of the Western Isles under the English crown[1372]. A charter dated [Jun 1297] records the crimes committed by "Alexandrum de Ergadia" against the English, signed by "Julianæ sponsæ nostræ"[1373]. m [Juliana MacDougall JULIANA], daughter of --- (-after [Jun 1297]). A charter dated [Jun 1297] records the crimes committed by "Alexandrum de Ergadia" against the English, signed by "Julianæ sponsæ nostræ"[1374]. Balfour Paul says that Alexander married "Juliana of Lorn, and by her had six sons John Dubh, Reginald, Somerled, Angus, Godfrey and Charles", adding that "these sons found their way to Ireland where they left numerous descendants", but does not cite the corresponding primary sources[1375].
>>>*ii) [Angus Og MacDonald of the Isles ANGUS Macdonald] (-Finlaggan Castle, Isla 1330). He succeeded his brother as Lord of the Isles.
>>>*iii) [John " Iain Sprangach" MacDonald JOHN Macdonald] . Balfour Paul names "John known as Iain Sprangach" as the third son of Angus and his wife, adding that he was the ancestor of "the Macdonalds of Ardmamurchan", but does not cite the corresponding primary source[1376].
>>*b) [Alexander Macdonald ALEXANDER Macdonald . "Angus filius Douenaldi" donated revenue to Paisley monastery by undated charter, witnessed by "Alexandro fratre meo…"[1377]. Balfour Paul says that Alexander was known as "Alastair Mor" and was ancestor of "the Alexanders of Menstrie, Earls of Sterling, and the Alexanders, Earls of Caledon, the MacAlisters of Loup, with their cadet families of Strathaird, Glenbarr and Torrisdal", but he does not cite the corresponding primary sources[1378].
>>*c) [Murchaid Macdonald MURCHAID Macdonald .]

>2. [Ruaidhri mac Raghnaill, Lord of Kintyre RUAIRI] . Balfour Paul states that "Roderick" inherited "North Kintyre, Bute and the lands of Garmoran, extending from Ardnamurchan to Gleneig", previously the possessions of his paternal uncle Angus, but does not cite the corresponding primary source[1379]. The Annals of Ulster record that "the sons of Raghnall, son of Somurlech” fought "the men of Sciadh" [Skye] in 1209 "wherein slaughter was inflicted on them"[1380]. m [NN ---]. The name of Ruairi’s wife is not known. Ruairi & his wife had two children:
>>*a) [Dubhghall mac Ruaidhri DUGALD] (-1268). The Saga of Eirspennill’s Hakon Hakon’s son records that "John, Duncan’s son, and Dugald, Ruadri’s son" met Alexander II King of Scotland in 1248 and "endeavoured…that the king should give them the title of king over the northern part of the Hebrides"[1381]. The Saga of Eirspennill’s Hakon Hakon’s son names "king Dugald, Alan Dugald’s brother, Angus and Murchaid" among those who met Haakon IV King of Norway when he invaded in 1263, adding in a later passage that the king gave "to [Dugald] the dominion that king John had had"[1382]. The Icelandic Annals record the death in 1268 of "Dubgallus rex Hebudum"[1383]. m ---. The name of Dugald’s wife is not known. Dugald & his wife had one child:
>>>*i) [Erik ERIK] .
>>*b) [Alan mac Ruaidhrí ALAN] (-after 1263). The Saga of Eirspennill’s Hakon Hakon’s son names "king Dugald, Alan Dugald’s brother, Angus and Murchaid" among those who met Haakon IV King of Norway when he invaded in 1263[1384]. m ---. The name of Alan’s wife is not known. Alan & his wife had three children:
>>>*i) [Christiana CHRISTIANA] . Robert I King of Scotland confirmed land "de Knodworache" to "Roderico filio Alani" by charter dated to [1320], which names "Cristina de Mar filia quondam Alani filii Roderici"[1385]. m [Donald de Mar, 6th Earl of Mar DUNCAN of Mar] son of ---.
>>>*ii) [Roderick MacRuare of Garmoran RUAIRI] . Robert I King of Scotland confirmed land "de Knodworache" to "Roderico filio Alani" by charter dated to [1320], which names "Cristina de Mar filia quondam Alani filii Roderici"[1386].
>>>*iii) [Lachlan LACHLAN] .

>*3. [[NN (Helen?) ---] (-before 1209). Balfour Paul says that Alan Lord of Galloway married first "a lady unknown, said to be a daughter of Reginald Lord of the Isles by whom he had two daughters"[1387]. He cites Chalmers’s Caledonia, but that says only that “the name of the first [wife] is unknown” without providing any indication of her family origin[1388]. Balfour Paul repeats his suggestion under the Lords of the Isles where he notes a daughter of Reginald Lord of the Isles "said to have married Alan of Galloway", without citing any source[1389]. There is no indication of the basis for Balfour Paul’s statements and no primary source which confirms this person’s parentage and marriage has been identified. Her existence should presumably be treated with caution until some such source emerges. If she did marry Alan, she was not the mother of his daughter Ellen. She was either married before his marriage to “--- de Lacy” or before he married Margaret of Huntingdon: she is shown here, for presentational purposes only, as Alan’s possible second wife. m as his [second] wife, [Alan mac Lochlan, Lord of Galloway ALAN Lord of Galloway], son of [Lochlann (Roland) mac Uchtred, Lord of Galloway, Constable of Scotland ROLAND Lord of Galloway] & his wife [Helen de Moreville Helen de Moreville] (-[2] Feb 1234, bur Dundraynan).]
