(b) _Maldred_ of Cumbria, whose eldest son was Gospatrick, and whose
second son was Dolfin; but with Maldred we are not concerned;

(c) _A daughter_, who became the mother of Moddan, whom Duncan
I, after his accession in 1034, created Earl of Caithness or Cat,
probably about 1040, his father being possibly of the family of Moldan
of Duncansby, whose sons Gritgard and Snaekolf, if we may believe the
_Njal Saga_, were slain by Helgi Njal's son and Kari Solmundarson,
Moldan being said to be a kinsman of Malcolm the Scots king.

2. Malcolm's second daughter, _Donada_, he married to Finnleac or
Finlay Mac Ruari, Maormor of North Moray, and a chief of the northern
Picts, and they had a son, Macbeth, born about 1005, who succeeded
Duncan I on his death in 1040 as King of Scotland, but left no
issue.[3]

3. Malcolm's third daughter, said to have been called _Plantula_, he
gave, about 1007, as his second wife to Sigurd Hlodverson, who, as we
have seen, was killed in 1014 at the decisive battle of Clontarf, his
wife having died probably before that event; and their only child was
a son, born about 1008 and created Earl of Caithness and Sutherland,
who became the great Earl and Jarl _Thorfinn_.

The three marriages were intended to secure to Malcolm the south,
the middle, and the north of Pictland through the fathers of Duncan,
Macbeth, and Thorfinn respectively; and we may note that from Thorfinn
are descended all subsequent Jarls and Earls of Orkney and Shetland
and Caithness of the so-called Norse line.
