Question: What two languages used anglo-frisian runes?

full_context: Document 1: Old Frisian: Old Frisian is a West Germanic language spoken between the 8th and 16th centuries in the area between the Rhine and Weser on the European North Sea coast. The Frisian settlers on the coast of South Jutland (today's Northern Friesland) also spoke Old Frisian but no medieval texts of this area are known. The language of the earlier inhabitants of the region between the Zuiderzee and Ems River (the Frisians mentioned by Tacitus) is attested in only a few personal names and place-names. Old Frisian evolved into Middle Frisian, spoken from the 16th to the 19th century.
Document 2: English language: English is a West Germanic language that was first spoken in early medieval England and is now a global "lingua franca". Named after the Angles, one of the Germanic tribes that migrated to England, it ultimately derives its name from the Anglia (Angeln) peninsula in the Baltic Sea. It is closely related to the Frisian languages, but its vocabulary has been significantly influenced by other Germanic languages, particularly Norse (a North Germanic language), as well as by Latin and Romance languages, particularly French.
Document 3: Caistor-by-Norwich astragalus: The Caistor-by-Norwich astralagus is a roe deer astragalus found in an urn at Caistor St. Edmund, Norfolk, England. The astragalus is inscribed with a 5th-century Elder Futhark inscription, reading raïhan "roe". The inscription is the earliest found in England, and predates the evolution of the specifically Anglo-Frisian Futhorc. As the urn was found in a cemetery that indicated some Scandinavian influence, it has been suggested that the astragalus may be an import, perhaps brought from Denmark in the earliest phase of the Anglo-Saxon settlement of Britain. The inscription is an important testimony for the Eihwaz rune and the treatment of Proto-Germanic "*ai". The "h" rune has the Nordic single-bar shape , not the Continental double-bar which was later adopted in the Anglo-Frisian runes.
Document 4: East Low German: East Low German (German: "Ostniederdeutsche Dialekte" ) is a group of Low German dialects spoken in north-eastern Germany as well as by minorities in northern Poland. Together with West Low German, it constitutes Low German. Before 1945, the dialect was spoken along the entire German Baltic Coast, from Mecklenburg, through Pomerania, West Prussia into certain villages of the East Prussian Klaipėda Region.
Document 5: Saxons: The Saxons (Latin: "Saxones" , Old English: "Seaxe" , Old Saxon: "Sahson" , Low German: "Sassen" , German: "Sachsen" , Dutch: "Saksen" , Welsh: "Saeson" ) were a group of Germanic tribes first mentioned as living near the North Sea coast of what is now Germany (Old Saxony), in the late Roman empire. They were soon mentioned as raiding and settling in many North Sea areas, as well as pushing south inland towards the Franks. Significant numbers settled in large parts of Great Britain in the early Middle Ages and formed part of the merged group of Anglo-Saxons who eventually organised the first united Kingdom of England. Many Saxons however remained in Germania (Old Saxony c. 531-804), where they resisted the expanding Frankish Empire through the leadership of the semi-legendary Saxon hero, Widukind. Initially, Saxons of Britain and those of Old Saxony (Northern Germany) were both referred to as 'Saxons' in an indiscriminate manner. The term Anglo-Saxon, in turn, came into practice in the 8th century (probably by Paul the Deacon) to distinguish English Saxons from continental Saxons (Ealdseaxe, 'old Saxons').
Document 6: Westerkwartier: The Westerkwartier (] ; English: Western Quarter ) is a historical region in the Dutch province of Groningen, at the border with the province of Friesland. In the past the area was part of the historical region of Frisia. The West Frisian language is still spoken in the western parts of the area (the villages Marum, De Wilp and Opende). In the rest of the Westerkwartier, "Westerkertiersk", a local variant of Low Saxon, is spoken.
Document 7: Anglo-Saxons: The Anglo-Saxons were a people who inhabited Great Britain from the 5th century. They comprise people from Germanic tribes who migrated to the island from continental Europe, their descendants, and indigenous British groups who adopted some aspects of Anglo-Saxon culture and language. Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman conquest.
Document 8: West Low German: West Low German, also known as Low Saxon (German: "Niedersächsisch" or German: "Westniederdeutsch" ; literally: "Nether-saxon"; Low German: "Nedersassisch, Nedersaksies, Platduuts, Plat(t)" ; Dutch: "Nedersaksisch" ; ) is a group of Low German (also Low Saxon; German: "Niederdeutsch" or "Plattdeutsch", Dutch: "Nederduits") dialects spoken in parts of the Netherlands, northwestern Germany and southern Denmark (in North Schleswig by the German minority). It is one of two groups of mutually intelligible dialects, the other being East Low German dialects.
Document 9: Northwest Germanic: Northwest Germanic is a proposed grouping of the Germanic languages, representing the current consensus among Germanic historical linguists. It does not challenge the late 19th-century tri-partite division of the Germanic dialects into North Germanic, West Germanic and East Germanic, but proposes additionally that North and West Germanic (i.e. all surviving Germanic languages today) remained as a subgroup after the southward migration of the East Germanic tribes, only splitting into North and West Germanic later. Whether this subgroup constituted a unified proto-language, or simply represents a group of dialects that remained in contact and close geographical proximity, is a matter of debate. The date by which such a grouping must have dissolved—in that innovations ceased to be shared—is also contentious, though it seems unlikely to have persisted after 500 AD, by which time the Anglo-Saxons had migrated to England and the Elbe Germanic tribes had settled in Southern Germany.
Document 10: Kings of the Angles: The Angles were a dominant Germanic tribe in the Anglo-Saxon settlement of Britain, and gave their name to the English, England and to the region of East Anglia. Originally from Angeln, present-day Schleswig-Holstein, a legendary list of their kings has been preserved in the heroic poems "Widsith" and "Beowulf", and the "Anglo-Saxon Chronicle".
Document 11: Anglo-Saxon runes: Anglo-Saxon runes are runes used by the early Anglo-Saxons as an alphabet in their writing. The characters are known collectively as the futhorc (or "fuþorc"), from the Old English sound values of the first six runes. The futhorc was a development from the 24-character Elder Futhark. Since the futhorc runes are thought to have first been used in Frisia before the Anglo-Saxon settlement of Britain, they have also been called Anglo-Frisian runes. They were likely used from the 5th century onward, recording Old English and Old Frisian.
Document 12: Alu (runic): The sequence alu () is found in numerous Elder Futhark runic inscriptions of Germanic Iron Age Scandinavia (and more rarely in early Anglo-Saxon England) between the 3rd and the 8th century. The word usually appears either alone (such as on the Elgesem runestone) or as part of an apparent formula (such as on the Lindholm "amulet" (DR 261) from Scania, Sweden). The symbols represent the runes Ansuz, Laguz, and Uruz. The origin and meaning of the word are matters of dispute, though a general agreement exists among scholars that the word represents an instance of historical runic magic or is a metaphor (or metonym) for it. It is the most common of the early runic charm words.
Document 13: Frankish language: Frankish (reconstructed Frankish: "*Frenkisk"), Old Franconian or Old Frankish was the West Germanic language spoken by the Franks between the 4th and 8th century. The language itself is poorly attested, but it gave rise to numerous loanwords in Old French. Old Dutch is the term for the Old Franconian dialects spoken in the Low Countries, ie. in present-day Belgium, in the present Netherlands and Western parts of today's Germany until about the 12th century when it evolved into Middle Dutch.
Document 14: Old English Latin alphabet: The Old English Latin alphabet—though it had no standard orthography—generally consisted of 24 letters, and was used for writing Old English from the 9th to the 12th centuries. Of these letters, 20 were directly adopted from the Latin alphabet, two were modified Latin letters (Æ, Ð), and two developed from the runic alphabet (Ƿ, Þ). The letters K, Q and Z were not in the spelling of native English words.
Document 15: Old Saxon: Old Saxon, also known as Old Low German, was a Germanic language and the earliest recorded form of Low German (spoken nowadays in Northern Germany, the northeastern Netherlands, southern Denmark, the Americas and parts of Eastern Europe). It is a West Germanic language, closely related to the Anglo-Frisian languages. It has been documented from the 8th century until the 12th century, when it gradually evolved into Middle Low German. It was spoken throughout modern northwestern Germany, primarily in the coastal regions and in the eastern Netherlands by Saxons, a Germanic tribe who inhabited the region of Saxony. It partially shares Anglo-Frisian's (Old Frisian, Old English) Ingvaeonic nasal spirant law which sets it apart from Low Franconian and Irminonic languages, such as Dutch, Luxembourgish and German.
