Fairbairn's Book of Crests of the Families of Great Britain and Ireland lists the following names as using the motto "Per mare, per terras" - which is the Latin equivalent.

Alexander, Courtayne, Darley, Drummond, Dupre, Durham, Lamb, Macalister, M'Alister, Macdonald, M'Donald, Madconnell, M'Eachern, M'Eachran, Macelester, Piessf, Rutherford, Rutherfurd, Urquhart, Warren-Darley
Of these there are several for which the crest is also some variation of "a dexter arm in armour embowed, holding a [sword, dagger, dirk, etc.]" These include, but are not limited to, Alexander (Ireland), M'Allister (Scotland), Macelester (Scotland).

So, really no closer, but interesting.
