Is there any point in searching for the testament of an Englishman or Englishwoman in Scottish records?

Probably not, unless you think there is a chance that he or she might have held some assets in Scotland, in which case you should definitely undertake this search. The registers of the principal commissary court in Edinburgh will be the ones to try. This court had responsibility in testamentary matters not only for Scots who died ‘furth of the realm’ but also for English people who may never have resided in Scotland but who held Scottish assets, even if it was only money in a Scottish bank account.
