There had always been a large number of Christians in the service of Raja Scindia at Gwalior State.
Angelo of Caraglio was working at Agra, Sardhana and Gwalior between the years 1817–1822.
It seems that due to lack of missionaries, people who were willing to become Christians were baptized without sufficient instruction to the catholic faith.
There was another group of Christians who had come from Goa in search of employment in the Scindia dominion.
Constant Fernandez, a Goan Diocesan Priest was the first residing chaplain of Lashkar and he laboured from 1832 to 1844.
During his stay he opened a school for the education of poor children, established an industrial centre for the employment of young girls and widows, provided the station with a burial ground and education uplift of his flock.
He was appointed Bishop of Derne and First Vicar Apostolic of Patna on 30 September 1845.
There have been 33 Chaplains from 1832 till it was dismembered from the Agra Archdiocese (established in 1886) and added the diocese of Jhansi on 5 July 1954.
