SriLanka is the large island off the coast of India. During the time of the UK Vice Royalty it was known as Ceylon. The pastor of my local church St Joseph’s Catholic LaCrosse WI diocese comes from there. Which strongly suggests that Roman interchange (St Thomas) was going on then.
For some reason my comment why I posted the above is missing because it brought back family memories of my father who after attending our midnight mass would insist on staying for St Steven’s mass which would follow it in early morning.
