I would like to know more about the history of the title "Kaur" in Sikhism.
After doing much research in to works such Gur sobha, Gur Bilas, and other primary sources of the 18th century and puratan rehatnamas and hukamnammas, I cannot find much evidence that this title was introducded on Vaisakahi day 1699.
Please refer to Mcleod's book Sikhs of the Khalsa: A history of the Khalsa Rahit, and Mcelod has stated that the title Kaur may have been introduced by the Singh Sabha movement in early 20th century.
Could you provide me with more information on this and any primary sources of the 17th or 18th century I can refer that can confirm that Kaur title was introduced in 1699.
Thank you.
