The 100 year old photograph lost, found and lost again

This photograph may have been taken in Warangal, Hyderabad State, (now Telangana, India) or Garla, Hyderabad State, (now Telangana India) more than hundred years ago, circa 1910.
The old man in the photograph is Mateti Ramanujana Rao and his wife Cheruku Ranganayakamma. And they were my great great grandparents.

The Maharanis of Travancore

It was in the fall of 1900, that the Maharajah of Travancore adopted the two girls in this photograph (taken in c. 1905), as his Maharanis — and as his ‘nieces’. For in Kerala, queens were never wives of monarchs, but their sisters. Under the matrilineal system of succession, ranks and titles passed in the female line; the Maharajah was a ruler not because his father was king before him, but because his mother was queen.
