Tripathi Sir,
Genealogy registers of Hindu families, maintained by Brahmin Pandits (Priests) or ‘Pandas’, who double up as professional genealogists, at Haridwar(other places in these records having records of Hindu families are Kurukshetra, Pehowa, Chintpurni, Jawalapur, and Jawalamukhi), has been a subject of study for many years now. In several cases, these voluminous records or Vahis (Bahi), have also been used in settling legal cases regarding inheritance or property disputes, as these records are held sacrosanct both by the pilgrims and the Pandas themselves, and in many places these records trace family history, for over twenty prior generations, stretching across many centuries
As per Sec 13.of Indian Evidence Act Facts relevant when right or custom is in question.-Where the
question is as to the existence of any right or custom, the following
facts are relevant:-
(a) any transaction by which the right or custom in question
was created, claimed, modified, recognized, asserted or
denied, or which was inconsistent with its existence:
(b) particular instances in which the right or custom was
claimed, recognized or exercised, or in which its
exercise was disputed, asserted or departed from.
And Sec 32 (7). When the statement is contained in any deed, will or
other document which relates to any such transaction as
is mentioned in section 13, clause (a).
or is made by several persons and expresses feelings relevant to
matter in question.
So as per my opinion the record of Genealogy registers of Hindu families, maintained Pandas at several places can be produce as evidence for the purpose deciding GOTRA in above said Sections cause they are more relevant.
Regard.
