I hesitate to share this because the veracity of it has never been historically verified.
My father's Indian great-great grandmother Kowlessure Bahadur Singh was born in 1861 in India. She is allegedly the posthumous daughter of Maharaja Maheshwar Singh Bahadur (died October 20, 1860). On the 26th of July 1886, she was examined by the British Surgeon Superintendent and the British Depot Surgeon at Port Calcutta and found to be 4'10" in height and to have a scar on her left calf (Emmigration Pass No. 476).
Kowlessure and her "husband" Gunais set sail Port Calcutta on the S.S. Foyle on 26 July 1886. Their children are as follows:
1. Ramnarayan (son) was born in 1877 in the Administrative District Mirzapur, NWFP (Modern Day Uttar Pradesh). At Port Georgetown, the imbecile of an Agent General of Immigration registered him as "Etwaroo."
2. Raghunandan (son) was born in 1886 aboard the SS Foyle.
3. Lachminia (daughter) was born in 1884.
4. Rambhoros (son) was born in 1875.
5. Dhun Bahadur Singh
6. Sirago
7. Bhogni Bahadur Singh (blonde hair, blue eyes)
8. Sundari
I have a copy of the original documents issued by officials of Her Majesty's Colonial Services. On the voyage was born a son by the name of Raghunandan in 1887. He was registered at Port Georgetown, British Guiana under the name "Etwaroo" (after the city of "Etawah" presumably).
PJ, can you add anything to this?
