I felt exactly the same a few years ago when I worked with an Indian fellow called
Brian (sic)!
Here's the scoop: Parts of southern
India were colonized by the Portugese. The city of Goa -- whose official language was Portugese until 1961! -- has a huge Catholic population, and many of the ethnically Indian population sport western names. Moreover, about 7% of the population of
Sri Lanka (formerly Ceylon) are
Christian, many of who carry western names. So dont be surprised the next time you meet a
Fernando Pinto from
India :)
