CHAPTER III.
NAMES OF SCANDINAVIAN ORIGIN.
Most of the Scandinavian names in the Isle of Man
have had the Celtic ' Mac ' prefixed, the contraction of
which has very much altered their form. These names
are not so common now as they were in the sixteenth
century.
AscouGH [15 1 1] (obsolete), from ask-iilfr, ' ash wolf.'
Casement, contracted from Mac-ds-Mundr. The
(O. N.) ds is equivalent to the Anglo-Saxon 6s, i.e.
seniideus, which we find in such names as Oswald
and OswY.
' Mu/idr was the sum the bridegroom had to pay for his
bride as agreed on at the espousals. It is used as the latter
part of several proper names.'*
Compare (O.N.) As-Mundr found in the Land-
ndmaboc and Flateyjarhoc.
MacCasmonde [1429], MacCasmund [1511], Casymound
Casmyn [1540]. Casmond [1601], Casement [1612],
COSTMINT [1624], CaISMENT [1679].
It is almost confined to the northern parishes.
It is not so common now as formerly.
Maughold, Lezayre (vc) formerly, Jurby, Ballaugh, Andreas
(c), elsewhere (u).
