Family reputation or tradition regarding pedigree
The reputation or tradition existing in a family previous to the controversy, in respect to the pedigree of any one of its members, may be received in evidence if the witness testifying thereon be also a member of the family, either by consanguinity or affinity. Entries in family bibles or other family books or charts, engravings on rings, family portraits and the like, may be received as evidence of pedigree. (Section 40 of Rule 130 of the Rules of Court)
