Mātā Sundarī (Gurmukhi: ਮਾਤਾ ਸੁੰਦਰੀ, Shahmukhi: ماتا سندری) was the most famous of the female followers of the last Sikh guru Gobind Singh. Mata Sundari was the daughter of Ram Saran of Lahore, and was married to Guru Gobind Singh in 1684. The couple had a child together: Ajit Singh. She holds a special place in Sikhism for the role she played in leading Sikhs through the troubled times that befell on them after the death of her husband and sons.

Guru Gobind Singh Ji (born: Gobind Rai) (Punjabi: ਗੁਰੂ ਗੋਬਿੰਦ ਸਿੰਘ [ɡʊɾu ɡobɪnd sɪ́ŋɡ], Marathi: गुरु गोबिंद सिंघ; 22 December 1666 - 7 October 1708) is the Tenth of Eleven Sikh Guru Ji'. Born in Patna, Bihar in India, He was also a Warrior, Poet and Philosopher. He succeeded His Father Guru Tegh Bahadur Sahib Ji as the Leader of Sikhs at a young age of nine. He contributed much to Sikhism; notable was His contribution to the continual formalisation of the faith which the First Sikh Guru Ji Guru Nanak Dev Ji had founded, as a religion, in the 15th century. Guru Gobind Singh transformed Sikhs into Khalsa (pure) in 1699.

Gobind Singh was born to Guru Tegh Bahadur, the ninth Sikh guru, and Mata Gujri in Patna. He was born while his father was on a tour of a neighbouring state Assam, spreading God's word. He learned Persian and Sanskrit when he was a child and was also trained to become a warrior.

Gobind Singh married three times and had four children. He was married off to Mata Jito in 1677, when he was only 11-years-old. They had three children together Zorawar Singh, Jujhar Singh and Fateh Singh. He married Mata Sundari in 1684, and the couple had one child, Sahibzada Ajit Singh. His third wife was Mata Sahib Dewan.

Amritpal Singh (born 6 October 1983) is an Indian track and field athlete from Punjab who specializes in long jump. He holds the current national record of 8.08 metres in long jump. On 16 March 2004, Amritpal broke one of the oldest national records in Indian athletics – T. C. Yohannan's 3-decade-old record in the long jump – by leaping to a distance of 8.08 metres in the 10th Federation Cup Athletics Championships at the Nehru Stadium in New Delhi.

Born on 6 October 1983 in Sangrur district of Punjab in India, Amritpal is only the third Indian to go beyond the magical eight-metre mark in the long jump; the others being T. C. Yohannan of Kerala and Sanjay Kumar Rai (8.02m and 8.03m in 2000) of Uttar Pradesh. He works for Punjab Police as an Inspector.

Though Amritpal had passed the qualifying norm of 8.05 m for the 2004 Athens Olympics, he was left out because of unsatisfactory form and fitness.

Mata Sahib Kaur (Gurmukhi: ਮਾਤਾ ਸਾਹਿਬ ਕੌਰ, Shahmukhi: ماتا صاحب کور) was the wife of the tenth Sikh guru Gobind Singh. Born Sahib Devan, she was the daughter of Ramu of Rohtas. She was declared as the mother of all the baptised Sikhs (the Khalsa).

Sahibzada Ajit Singh Ji (1687–1705) was the eldest of Guru Gobind Singh Ji's four sons. His younger brothers were Sahibzada Jujhar Singh Ji, Sahibzada Zorawar Singh Ji and Sahibzada Fateh Singh Ji. With his three brothers, Sahibzada Ajit Singh Ji carried on a family tradition: that of attaining the status of one of the most hallowed martyrs in Sikh history. Before him and his brothers, their grandfather, the Ninth Sikh Guru Ji, Guru Tegh Bahadur Sahib Ji and his great-great grandfather, the Fifth Sikh Guru Ji, Guru Arjan Dev Sahib Ji had also been executed by the Mughals.

Sahibzada Ajit Singh Ji was born to Mata Sundari Ji and Guru Gobind Singh Ji at Paonta Sahib on 3 January, 1687. The following year, Guru Gobind Singh Ji returned with the family to Anandpur where Sahibzada Ajit Singh Ji was brought up in the approved Sikh style. He was taught religious texts, philosophy and history, and had training in the manly arts such as riding, swordsmanship and archery. He grew up into a handsome young man; strong, intelligent and a natural leader of men.
