🧬 Origin of the surname “Nattoo”

Likely linguistic roots

Because of its rarity, researchers usually analyze similar surnames:

1. Indo-Caribbean / Indian origin (most plausible)

• A closely related surname is “Nathoo”, which comes from the Sanskrit root “Nath” meaning “lord” or “protector.”
• During the 19th century, many Indians were brought to the Caribbean (including Jamaica) as indentured laborers.
• Names were often:
  • Phonetically altered
  • Misspelled by colonial record keepers
  • Adapted to English spelling

👉 This makes Nattoo likely a variant of Nathoo / Nath / Nathu-type names.
