cher ami Soobhanund Seeparsad, Salut et je suis mauricien comme toi.  Moi aussi je cherche le village de mon ancetre, c-a-dire mon arriere arriere grandpere au Bihar.  Je vais continuer en anglais enfin que tout le monde puisse lire.My ancestor came from Bihar, India in June 1858 to Mauritius to work as labourer. He was my great great grandfather. I have always wanted to know from which village/place he was from and even, visit the village, Godwiling, one day.
In September 2009, I have been able to trace my ancestor who came to Mauritius. According to records available at the Indian Immigration Museum in Mauritius as recorded in June 1858, he was from:
My great great grandfather was from
Village: Nurunjempore
Zillah: Arrah
Pergunnah: Bhojepore
(State of Bihar, India)          
He arrived in Mauritius on 07 June 1858  Port of Embarkation: Calcutta.
From my research, I understand that the Sub-district of Bhojepore of 1858 is now divided into more districts namely  Bhojpur, Rohtas, Buxar and Kaimur .  Thus, the village of Nurunjempore (now written as Niranjanpur) in the Sub-district of Bhojepore (of 1858) as recorded could be located in any of the districts: Arrah/Bhojpur or nearby districts of Rohtas, Buxar and Kaimur.
I have done some internet search to locate that village in Bihar from such websites as: http://www.maavooru.net (now difficult to access now) and www.brandbihar.com According to these websites, there are 5 “Niranjanpur” in Rohtas(two), Buxar(two) and Kaimur(one) altogether.  Check if Sub-district of Piro is divided further, and get how it is spelt now and surf on www.brandbihar.com.  I can not continue I have arrived at the word limit.  Bonne chance and mes meilleurs voeux.
