How we know what we know

What the research set out to answer

The report this site is built on was constructed around six questions Ninglekhu/ku heritage documentation project 2026 C:

1. What can be established about the Ninglekhu/ku thar specifically — its attestation, its place in Limbu clan classification, its geography, its etymology, and the people who carry the name?
2. What is the wider Limbu history into which any single clan’s story has to be set — and which parts of it are documented rather than asserted?
3. Where do the standard accounts disagree, and where does a widely repeated claim turn out to have no source behind it?
4. What media and archival assets exist that a community website could lawfully publish?
5. What methods should a clan use to generate the evidence that does not yet exist — oral history, genealogy, community archiving?
6. What editorial standard would make such a site trustworthy to a family member, a school student, a journalist and a researcher at the same time?

Geographically the work covers the historic Limbuwan (Pallo Kirat) — today the eastern districts of Koshi Province — together with Sikkim and the Darjeeling–Kalimpong hills, and the global diaspora. Chronologically it runs from the classical attestation of the term Kirāta to developments recorded up to early 2025, with a note wherever the trail goes cold before the present day.

What was searched, and how

The research was run as a set of parallel, independently briefed enquiry streams, each instructed to record a verbatim quotation and a source URL for every claim and — crucially — to report failure explicitly rather than fill a gap with inference. The streams covered Ninglekhu/ku-specific evidence; Limbu ethnogenesis and Kirat historiography; the political history of Limbuwan; Mundhum, religion and script; social structure and customary law; modern demography and diaspora; and the media asset inventory. An eighth stream was tasked solely with attacking the gaps the first seven had left open. Roughly 550 distinct source retrievals were attempted Ninglekhu/ku heritage documentation project 2026 C.

The sources consulted include Nepal’s census reports National Statistics Office, Nepal 2021 Central Bureau of Statistics, Nepal and the NFDIN Act Government of Nepal 2002 A; NepJOL journals, Tribhuvan University theses, Dambar Chemjong’s Cornell dissertation Chemjong, Dambar Dhoj 2017, Martin Gaenszle’s articles Gaenszle, Martin 2021, population-genomic work in Current Biology, Scientific Reports, Human Genetics and Nature Communications, and the Sino-Tibetan etymological database Sino-Tibetan etymological database — the Limbu lexical dataset B; Ethnologue Limbu [lif], the Sikkim Tribal Research Institute Tribal Research Institute, Government of Sikkim and Kirat Yakthung Chumlung Kirat Yakthung Chumlung (Nepal), and Kirat Yakthung Chumlung UK C; and a range of community-compiled thar lists and heritage sites E.

The five grades

Every substantive claim carries a letter. The scheme is deliberately simple, and it is offered for reuse by other clan projects — copy it, or write your own, but use one and publish the key Ninglekhu/ku heritage documentation project 2026 C.

What the grades do not say

The most important thing about the scheme is what it does not say. Grade E is not a synonym for “false.” A Mundhum narrative is authoritative testimony about what a community holds to be true, and it is the only source we have for most of Limbu religious and moral life. What the grade records is the kind of claim a source can carry: a grade-E source can establish that a story is told; it cannot establish that an event occurred. Both statements are worth publishing — but not in the same typeface, and not without saying which is which.

Grade D deserves particular care. Iman Singh Chemjong (1904–1975) is simultaneously the foundation of modern Limbu self-knowledge and a source that professional historians now read as evidence for the history of Limbu nationalism rather than as a settled account of the ancient past Chemjong, Iman Singh 1948–1974 D. Both things are true at once, and a clan website should be able to say so without embarrassment on either side.

Two further rules follow from the grades and are applied everywhere on this site. Repetition never promotes a claim: if forty websites say the same thing and none cites a document, the claim is still grade E. And anything current is date-stamped — “as of February 2025” is honest; “currently”, written in 2025, is quietly wrong by 2027.
