Question: Who was the father of the person Þórðr Kolbeinsson was the court poet for?
Context: Bernardo Bellincioni (1452–1492) was an Italian poet, who began his career in the court of Lorenzo the Magnificent in Florence.  In 1483 he was at the Gonzaga court and in 1485 he moved to Milan, where he was the court poet of Lodovico Sforza, the patron of Leonardo da Vinci.  He wrote eulogistic sonnets addressed to his patrons and engaged in the usual literary squabbles with other poets, some in the burlesque manner established by Domenico Burchiello, that are a characteristic of the Italian Renaissance. The forefathers of the poet came to Tamil Nadu to sell perfumes and settled in Nagalapuram, before moving to Ettayapuram where the poet was born.  Umaru Pulavar’s literary talents flourished under Kadikai Muthu Pulavar that is only in Tamil launguage (Tamil: கடிகை முத்து புலவர் ), court poet of the Ettayapuram Zamin.  At the age of 16, Umaru Pulavar stole the national limelight by winning a literary debate with Vallai Varundhi, a renowned poet from North India.  Umaru Pulavar was then made the court poet of the Ettayapuram Zamin.  But he was not able to learn Arabic grammar.  While learning the Arabic language his master went for his essential work for earning money.His family and heirs were awarded with Pulavar title by government of Tamil Nadu, and they carry the initial before their bio initial.  PF Nazeer, one of the last heir with some unpublished work poems died recently of cancer.His family has set up a trust for education and social reforms for poor people on his anniversary. Þórðr Kolbeinsson ("Thordr Kolbeinsson") was an 11th-century Icelandic skald, or poet.

He was a native of Kalandai in Thondaimandalam.  He was famous for authoring "Thondaimandala Sadhakam", a poetic collection written in praise of Thondaimandala Vellalars or agriculturists.  He had also authored "Thandalaiyar Sadhakam".  He was a court poet of Raghunatha Kilavan, first Sethupathi of Ramnad.  The poet was a contemporary of Kalamega Pulavar.

Þórðr Sjáreksson was an 11th-century Icelandic skald.  He composed a "drápa" on Þórólfr Skólmsson, four strophes of which have been preserved in the kings' sagas.  He also composed a memorial "drápa" on the canonised Olaf II of Norway, called "Róðadrápa" ("Drápa of the Rood"), one strophe of which is preserved.  A few disjoint strophes by Þórðr on different subjects are also preserved in "Skáldskaparmál". " Skáldatal" reckons Þórðr among the court poets of both Óláfr Haraldsson and Eiríkr Hákonarson. Y Prydydd Bychan (fl.  c. 1222-68) was a medieval Welsh language court poet.  His personal name is unknown.  His father was the poet Phylip Brydydd.  "Prydydd" was a grade of court poet, and "bychan" here has the meaning "junior" (somebody's son) rather than the more usual "small" or "little", presumably to distinguish him from his father.

He was the son of another poet, Meilyr Brydydd, and father of the poets Meilyr ap Gwalchmai and Einion ap Gwalchmai.  He shares his name with Gwalchmei ap Gwyar, a figure from Welsh legend described as the nephew of Arthur and known in English as Gawain.

Arnórr Þórðarson jarlaskáld ("Poet of Earls") (c. 1012 - 1070s) was an Icelandic skald, son of Þórðr Kolbeinsson.  Arnórr travelled as a merchant and often visited the Orkney Islands where he composed poems for the Earls, receiving his byname.  For king Magnus the Good he composed "Hrynhenda".
