Traditional British surnames — English, Scottish, Welsh, and Irish family names centuries old in Britain — appear on Tamil Christian families for a reason: five centuries of missionary contact. Portuguese Catholics from the 1500s, Danish Lutherans from 1706, Anglican and Wesleyan missions from the 1800s, and modern CSI, all left British surnames on Tamil converts and their descendants.
The four source patterns
- Missionary sponsor — the officiating missionary’s surname passed to the convert’s family.
- Baptismal adoption — a Christian first name (David, Peter, Samuel) became a hereditary surname.
- Anglicised patronymic — the father’s Tamil first name became the British-record surname.
- Genuine British descent — a rare pattern via soldier, planter or civil servant marriage.
The archives that document each pattern
- Roman Catholic missions — RC diocesan and parish registers, Nagapattinam, San Thome Chennai, Puducherry.
- Danish Lutheran — Franckesche Stiftungen, Halle, Germany.
- Anglican (CMS, SPG) — Lambeth Palace Library, Rhodes House Oxford, Bodleian.
- Wesleyan Methodist — SOAS, University of London.
- CSI (post-1947) — CSI diocesan archives.
- British-Indian marriages (genuine descent) — India Office Records at British Library (IOR/N series).
