It broadly refers to people who are descendants in an unbroken male line from a common male ancestor or patriline.  Generally the gotra forms an exogamous unit, with the marriage within the same gotra being prohibited by custom, being regarded as incest.  The name of the gotra can be used as a surname, but it is different from a surname and is strictly maintained because of its importance in marriages among Hindus, especially among the higher castes.  Pāṇini defines "gotra" for grammatical purposes as "apatyam pautraprabhrti gotram" (IV.  1.  162), which means "the word "gotra" denotes the progeny (of a sage) beginning with the son's son."  When a person says "I am Vipparla -gotra," he means that he traces his descent from the ancient sage Vipparla by unbroken male descent.

Suraiya Jamaal Sheikh (15 June 1929 – 31 January 2004), popularly known as Suraiya, was an Indian Muslim Hindi/Hindustani film actress and playback singer in Bollywood from the 1940s to the early 1960s, who remained unmarried throughout her life, after her love affair with actor Dev Anand was aborted by her maternal grandmother.  She was the most popular singing star of the Indian sub-continent of her generation.  Until 1943, as a child singer, Suraiya did playback singing for one actress, namely Mehtab, in three films, and also in some of her own films for her roles as a child artiste.  After this, she only sang for her own films as an actress, and acted as a heroine from 1946 until the end of her career in 1963.  From 1948 to 1951, she became the singing superstar of Bollywood, earning more for her performances than all the performing actors of the times, male or female, including Dev Anand, Raj Kapoor, Dilip Kumar, Nargis and Madhubala.  She received 1.5–2 lakhs rupees for her role per film, when top male actors were getting 50 thousand to 1 lakh rs.  For a song, she commanded rs. 1000, while Lata Mangeshkar was getting rs. 100–200 per song.  She was the only child of her parents.  She had a natural talent for singing, acting and dancing from childhood.  She received basic training in music when her mother used to take her to a Hindustani music teacher or 'masterji' for training.  She first sang for a children's program for All India Radio in 1937.  Later on Naushad gave her on the job 'training', while recording.  She went on to become one of the most successful singing film stars of Bollywood.

Suraiya in her heyday was known as 'Malika-e-Husn' (queen of beauty), 'Malika-e-Tarannum' (queen of melody) and 'Malika-e-Adakaari' (queen of acting), all rolled into one.  In a career spanning from 1936 till 1963, Suraiya sang 338 songs in films (which were mostly her own films) and 2 in addition were non-film songs, namely, 'tum rahe kahan ko piya' and 'hum tum karenge pyar'.  She acted in 67 movies, which do not include the incomplete films such as "Jaanwar" (with Dilip Kumar), "Paagal Khaana" with Bharat Bhushan and an Indo-British film on Wajid Ali Shah (1953) being directed by British director, Herbert Marshall, with Ashok Kumar in the role of Wajid Ali Shah. The Strickland, later Cholmley, later Strickland-Constable Baronetcy, of Boynton in the County of York, is a title in the Baronetage of England.  It was created on 30 July 1641 for the politician William Strickland.  He was summoned to Oliver Cromwell's House of Lords as Lord Strickland.  The second Baronet sat as Member of Parliament for Beverley during the Commonwealth.  The third Baronet was a politician and racehorse owner.  The fourth Baronet was also a politician and served as Secretary at War from 1730 to 1735.  The seventh Baronet was a barrister and Whig politician.  He married Mary, daughter and heiress of Reverend Charles Constable, of Wassand.  In 1865 he succeeded to the substantial estates of Nathaniel Cholmley and assumed the same year by Royal permission the surname of Cholmley in lieu of his patronymic for himself and those of his heirs male who may succeeded to the Cholmley estates.  However, his son and successor, the eighth Baronet, reverted to the use of the surname of Strickland.  The ninth Baronet became a Czechoslovakian citizen and did not use his title.
