Act or declaration about pedigree
The act or declaration of a person deceased, or unable to testify, in respect to the pedigree of another person related to him by birth or marriage, may be received in evidence where it occurred before the controversy, and the relationship between the two persons is shown by evidence other than such act or declaration. The word "pedigree" includes relationship, family genealogy, birth, marriage, death, the dates when and the places where these fast occurred, and the names of the relatives. It embraces also facts of family history intimately connected with pedigree. (Section 39 of Rule 130)
