When a Tamil family carries an English first name AND an English surname, the pattern is almost always Tamil Christian conversion, not English descent. Understanding how the naming worked in each of the missionary denominations helps you know where to look for the actual paper trail.
The pattern by denomination
- Roman Catholic — Portuguese-Latin baptismal names (Antonio, Maria, Fernandes, Rosario) predominated in the 1500s–1700s; English-language equivalents replaced them under British-era clergy after 1800.
- Danish-Halle Lutheran (Tranquebar, from 1706) — Old Testament first names (Isaac, Jacob, Elias, Moses) with the father’s baptismal name as surname.
- Anglican / CMS / SPG (Tirunelveli, Ramnad, Madras, from early 1800s) — English biblical first names (David, Peter, Samuel) with either the missionary’s surname or the father’s name as surname.
- Wesleyan Methodist (Madras, from 1817) — similar pattern to Anglican, often with Welsh or English regional surnames.
- CSI (post-1947) — combined Anglican/Wesleyan patterns continued.
