Robert de Montgomery, Baron of Eaglesham (also ancestor o
f Robert II of Scotland and Mary Stuart) settled in Scotlan
d and married Marjory Steward, daughter of Walter the Hig
h Steward. Robert died ca 1179 and was also known as Mac Ci
mbr. His sons were William, Hugh the eldest, and our anexto
r Alan de Montgomery.

SETTLEMENTS OF ENTAIL AND THE NAME OF MONTGOMERY
BEFORE passing on to the British branches of the family i m
ust be remarked that the name of Montgomery in England Scot
land and Ireland is borne also by others than those who hav
e a lineal descent from the ancient Norman family. This i
s first of all owing to the fact that names in these countr
ies sometimes follow settlements of entail; in other words
, they follow land instead of ancestry. There are also inst
ances where the name ol Montgomery has been adopted for oth
er reasons. On the other hand, it must be noted that certai
n branches of the family use other names, which have been a
ssumed in accordance with settlements of entail.
The sixth Earl, Alexander Seton, adopted for himself and hi
s descendants the names of Eglinton and Montgomery as hei
r to the estate of the fifth Earl (vide p. 115). From the p
oint of ancestry he was a Seton, but his father, Robert, fi
rst Earl of Winton and first Lord Seton, married Margaret
, daughter of Hugh, third Earl of Eglinton, who was a Montg
omery by lineal descent.
There is a practice that the descendants of the sixth Ear
l spell their names with ie at the end, which means Seton b
y ancestry, while the lineal descendants of the Norman Mont
gomerys spell the name with a y.
Certain members of the family of Herbert also use the nam
e Montgomery. Richard Herbert, Esquire, who lived during th
e latter part of the sixteenth century, was the owner of th
e lands of Montgomery Castle in Wales. These lands were inh
erited by his son, first Lord Herbert of Cherbury, who at o
ne time was British Ambassador in Paris. His kinsman, Phili
p Herbert, a younger son of the second Earl of Pembroke, wa
s one of the favourites of James 1. On 9th February 1606 h
e was created Earl of Montgomery, the Montgomery Castle lan
ds being handed over to him. This is the reason why the Ear
ls of Pembroke have adopted the title of Earls of Montgomer
y. Even such a well-informed source as Larousse is ignoran
t of these facts. Lord Herbert of Cherbury, who signed hims
elf de Montgomery as owner of the Montgomery estates in Wal
es, has by Larousse been mistaken for a Montgomery of Norma
n descent.
The family Lyons-Montgomery of Belhavel are Lyons by descen
t, but on the female side their ancestry includes a Montgom
ery. Equally the family Montgomery of Carboldisham are Moly
neux by lineal descent but include a Montgomery.of Broomlan
ds in their ancestry.
Arnulf de Montgomery was at one time Castellan of Pembrok
e Castle. He was succeeded in this office by Gerald, son o
f Walter Fitz Otho, Castellan of Windsor Castle. The famil
y of Carew are said by some to be descended from Arnuff, wh
ile others state that Gerald was their ancestor.
Camden says: 'Upon another creeke also of this haven, Care
w Castle sheweth itselfe, which gave both name and original
l to the notable family de Carew, who avouche themselves t
o have been called aforetime de Montgomery; and have been p
ersuaded, that they are descended from Arnulf de Montgomer
y of whom I spake erwhile' (Britannica, ed. 1637, 651-2).
