Input: Question: Where does the route begin that 104 intersects with in Stamford? Passage 1:Irene was daughter of despotēs Theodore Komnenos Doukas, ruler of Epirus, and Maria Petraliphaina (sister of the sebastokratōr John Petraliphas). In 1230 Irene and her family were captured by the troops of tsar Ivan Asen II of Bulgaria in the battle of Klokotnitsa and they were taken in Tarnovo, where Irene grew up in the Palace. Irene became known for her beauty and the widowed tsar fell in love with her. They married in 1237. According to a Byzantine author, Ivan Asen II loved Irene "no less than Antony loved Cleopatra", and she may have been his mistress for some years before their marriage in 1237. By marrying Irene, Ivan Asen II would have broken church canons, as his daughter, Maria Asanina Komnena, from his marriage to Anna (Anisia) was married to Irene's uncle, Manuel of Thessalonica. There is some evidence that the Bulgarian church opposed the marriage and that a patriarch (called either Spiridon or Vissarion) was deposed or executed by the irate tsar.
 Passage 2:Route 104 begins at an intersection with Route 137 in the Bulls Head section of Stamford and heads north, passing by GE Capital, then crossing the Rippowam River, up through North Stamford and onto New York state line. About north of the river, Route 104 crosses under the Merritt Parkway (Route 15) at Exit 34 into the North Stamford section of the city. After another , Route 104 crosses over the Mianus River, through the Long Ridge section of the city, as it heads towards the New York state line. The road ends in the town of Pound Ridge, New York and continues as Westchester County Road 3. Route 104 is known as Long Ridge Road throughout its length and is classified as a principal arterial road, carrying traffic volumes of as much as 30,000 vehicles per day, particularly near the Merritt Parkway interchange. Route 104 is four lanes wide from Route 137 to Route 15, and two lanes wide north of Route 15.
 Passage 3:Dido Elizabeth Belle was born into slavery in 1761 in the British West Indies to an enslaved African woman known as Maria Belle. (Her name was spelled as Maria Bell in her daughter's baptism record.) Her father was 24-year-old Sir John Lindsay, a member of the Lindsay family of Evelix branch of the Clan Lindsay and a descendant of the Clan Murray, who was a career naval officer and then captain of the British warship HMS Trent, based in the West Indies. He was the son of Sir Alexander Lindsay, 3rd Baronet and his wife Amelia, daughter of David Murray, 5th Viscount Stormont. Lindsay is thought to have found Maria Belle held as a slave on a Spanish ship which his forces captured in the Caribbean; he appears to have taken her as his concubine (see plaçage). Lindsay returned to London after the war in 1765 with his young daughter, Dido Belle. When they arrived in England he took her to Kenwood House just outside the city, the home of his uncle, William Murray, 1st Earl of Mansfield, and his wife Elizabeth Murray, Countess of Mansfield. Belle was baptised as Dido Elizabeth Belle in 1766 at St. George's, Bloomsbury. The Murray family raised Belle as an educated woman along with their niece and Dido's cousin, Lady Elizabeth Murray, whose mother had died. However, Belle remained a slave until Mansfield finally granted her freedom from slavery in his will in 1793.
