It could be Fourth Declension and be Straxus with a long U [like 'goose'].As has mine.
Mercy is not dispensed here. Only Straxuses (Straxi? Straxusses? I'm not sure on how to pluralize it)
Or if it's originally Greek, Straxes.
(I am certain Straxus was not Greek. His palm tree suggests he or his forbears migrated from somewhere more tropical.)
