Question: In what kingdom that is bordered by Epirus to the west, Paeonia to the north, Thrace to the east and Thessaly to the south did the Trocmi tribe reside?
Context: The Trocmii or Trocmi were one of the three ancient tribes of Galatia in central Asia Minor, together with the Tolistobogii and Tectosages, part of the possible Celtic group who moved from Macedonia into Asia Minor in the early third century BCE. The Roman province of Macedonia (Latin: "Provincia Macedoniae" , Greek: Ἐπαρχία Μακεδονίας ) was officially established in 146 BC, after the Roman general Quintus Caecilius Metellus defeated Andriscus of Macedon, the last self-styled King of the ancient kingdom of Macedonia in 148 BC, and after the four client republics (the "tetrarchy") established by Rome in the region were dissolved.  The province incorporated ancient Macedonia, with the addition of Epirus, Thessaly, and parts of Illyria, Paeonia and Thrace.  This created a much larger administrative area, to which the name of 'Macedonia' was still applied.  The Dardanians, to the north of the Paeonians, were not included, because they had supported the Romans in their conquest of Macedonia. Epirus ( ; Greek: Ήπειρος , "Ípeiros"), formally the Epirus Region (Περιφέρεια Ηπείρου, "Periféreia Ipeírou"), is a traditional geographic and modern administrative region in northwestern Greece.  It borders the regions of West Macedonia and Thessaly to the east, West Greece to the south, the Ionian Sea and Ionian Islands to the west and Albania to the north.  The region has an area of about 9,200 km2 .  It is part of the wider historical region of Epirus, which overlaps modern Albania and Greece but lies mostly within Greek territory. Sintice or Sintike (Greek: Σιντική) was an ancient region and later district of the kingdom of Macedon.  It was located north of Bisaltia and Odomantike up to Messapio mount and west of Crestonia and South Paeonia to Strymon river and Orvilos mount.  Its name is derived from the Sintians, a tribe which once inhabited the region.  Beyond it, it was stretched Medike which was held by the powerful Thracian tribe of Medi with which the Macedonians were in constant wars. Elimiotis or Elimeia or Elimaea (Ancient Greek: Ἐλιμιώτις or Ἐλιμία or Ἐλίμεια ) was a region of Upper Macedonia that was located along the Haliacmon, north of Perrhaebia/Thessaly, west of Pieria, east of Parauaea, and south of Orestis and Eordaea and was inhabited by the ancient Greek tribe of Elimiotes (Ancient Greek: Ἐλιμιῶται ).  In earlier times, it was independent, but later was incorporated into the Argead kingdom of Macedon.  Its capital was Aiane and Derdas family ruled the local Kingdom before incorporation into Macedon.  By 355 BC, Elimiotis was part of the Kingdom of Macedonia. Epirus ( ; Northwest Greek: Ἄπειρος , "Ápeiros"; Attic: Ἤπειρος , "Ḗpeiros") was an ancient Greek state, located in the geographical region of Epirus in the western Balkans.  The homeland of the ancient Epirotes was bordered by the Aetolian League to the south, Thessaly and Macedonia to the east, and Illyrian tribes to the north.  For a brief period (280–275 BC), the Epirote king Pyrrhus managed to make Epirus the most powerful state in the Greek world, and his armies marched against Rome during an unsuccessful campaign in Italy. Edonis or Edonida (Ancient Greek: Ἠδωνίς, Ἠδωνίδα ) also transliterated as Edonia, was an ancient region of Thrace which later became a district of Macedon.  Its name is derived from the ancient Thracian inhabitants of the region, the Edonians.  It was bordered by Odomantice in the north, Bisaltia in the west, Aegean Sea in the south, and was separated from Thrace proper by the river Nestos in the east. The Provisional Government of Western Thrace (Ottoman Turkish: غربی تراقیا حكومت موقته‌سی - "Garbi Trakya Hükûmet-i Muvakkatesi", Greek: Προσωρινή Κυβέρνηση Δυτικής Θράκης , "Prosorini Kyvernisi Dytikis Thrakis", Turkish: "Batı Trakya Geçici Hükûmeti" ), later renamed to Independent Government of Western Thrace (Ottoman Turkish: غربی تراقیا حكومت مستقله‌سی - "Garbi Trakya Hükûmet-i Müstakilesi", Greek: Αυτόνομη Κυβέρνηση Δυτικής Θράκης , "Avtonomi Kyvernisi Dytikis Thrakis"), was a small, short-lived partially recognized republic established in Western Thrace from August 31 to October 25, 1913.  It encompassed the area surrounded by the rivers Maritsa (Evros) in the east, Mesta (Nestos) in the west, the Rhodope Mountains in the north and the Aegean Sea in the south.  Its total territory was c. 8.600 km². Macedonia or Macedon ( , ] , Greek: Μακεδονία , "Makedonía ") was an ancient kingdom on the periphery of Archaic and Classical Greece, and later the dominant state of Hellenistic Greece.  The kingdom was founded and initially ruled by the royal Argead dynasty, which was followed by the Antipatrid and Antigonid dynasties.  Home to the ancient Macedonians, the earliest kingdom was centered on the northeastern part of the Greek peninsula, and bordered by Epirus to the west, Paeonia to the north, Thrace to the east and Thessaly to the south. Central Greece Region (Greek: Περιφέρεια Στερεάς Ελλάδας , "Periféreia Stereás Elládas", properly translated as "Continental Greece Region") is one of the thirteen administrative regions of Greece.  The region occupies the eastern half of the traditional region of Central Greece, including the island of Euboea.  To the south it borders the regions of Attica and the Peloponnese, to the west the region of West Greece and to the north the regions of Thessaly and Epirus.  Its capital city is Lamia.
