He was described as french by Ram Babu Saksena in his book  'A History of Urdu Literature' (here). What is intriguing is that he lived in 18th century and died in 1802. It is hard to comprehend that a gora in that period having such closeness with budding language of Urdu. There is no formal collection of his work but this sher is described.
