Indians and Their Biblical Last Names—

I asked JY why some Indians have American last names.  She corrected me and responded, “You mean biblical last names?”  Then she went on to tell me that when Thomas came to India, lot of Indians changed their last names to Biblical names upon conversion b/c their native last names had references to Hindu deity.  So, the explanation was that if you see an Indian w/ Biblical last names, they probably have a Christian heritage.  This confirmed another thing…I thought Thomas going to India was only a tradition, which wasn’t verified.  But she said it was passed down as an oral tradition but was still very reliable.  And this change of the last names is the living proof of that story being true.
