You can try the UserSearchService

import com.atlassian.jira.component.ComponentAccessor

def users = ComponentAccessor.userSearchService.findUsersByFullName('Peter-Dave Sheehan')
if(users.size()>0){
  return users.first()
}

Hello @PD Sheehan ,

Thanks, it worked.

I found the complete script: 

import com.atlassian.jira.bc.user.search.UserSearchService
import com.atlassian.jira.component.ComponentAccessor

def userSearchService = ComponentAccessor.getComponent(UserSearchService)
def users = userSearchService.findUsersByFullName("Mr Admin")

if (users) {
    users.first() // an ApplicationUser (in jira 7)
}
else {
    // no users found with that display name
}
