Withdrawn — Withdrawn 2026-07-27. Ranked first at 1820, a year taken from Grokipedia — an AI-generated encyclopaedia this site cannot cite. RPSG Group's own timeline says only "Early 1800s, Ramdutt Goenka arrived in Kolkata, from Dhunlod in Rajasthan", which cannot support a dated rank on a documented_date list. His Marwari identity could not be independently sourced either: RPSG records a later Goenka as the first Marwari to graduate from Presidency College in 1905, who is a different man. He belongs in this record; the research does not yet exist to put him back.
Migrated from Dundlod in Shekhawati and established himself in Calcutta as a banker, then as an agent for British commercial interests — the earliest of the three houses on this list.
