  Part IV
  Of Consanguinity
  23. Application of Part.-
  Nothing in this Part shall apply to any will made or intestacy occurring before the first day of January, 1866, or to intestate or testamentary succession to the property of any Hindu, Muhammadan, Buddhist, Sikh, Jaina or Parsi.
  24. Kindred or consanguinity.-
  Kindred or consanguinity is the connection or relation of persons descended from the same stock or common ancestor.
  25. Lineal consanguinity.-
  (1) Lineal consanguinity is that which subsists between two persons, one of whom is descended in a direct line from the other, as between a man and his father, grandfather and great-grandfather, and so upwards in the direct ascending line; or between a man andhis son, grandson, great-grandson and so downwards in the direct descending line.
  (2) Every generation constitutes a degree, either ascending or descending.
  (3) A person's father is related to him in the first degree, and so likewise is his son; his grandfather and grandson in the second degree; his great-grandfather and great-grandson in the third degree, and so on.
  26. Collateral consanguinity.-
  (1) Collateral consanguinity is that which subsists between two persons who are decended from the same stock or ancestor, but neither of whom is descended in a direct line from the other.
  (2) For the purpose of ascertaining in what degree of kindred any collateral relative stands to a person deceased, it is necessary to reckon upwards from the person deceased to the common stock and then downwards to the collateral relative, a degree being allowed for each person, both ascending and descending.
  27. Persons held for purpose of succession to be similarly related to deceased.-
  For the purpose of succession, there is no distinction-
  (a) between those who are related to a person deceased through his father, and those who are related to him through his mother; or
  (b) between those who are related to a person deceased by the full blood, and those who are related to him by the half blood; or
  (c) between those who were actually born in the lifetime of a person deceased and those who at the date of his death were only conceived in the womb, but who have been subsequently born alive.
  28. Mode of computing of degrees of kindred.-
  Degrees of kindred are computed in the manner set forth in the table of kindred set out in Schedule I.
  Illustrations
  (i) The person whose relatives are to be reckoned, and his cousin-german, or first cousin, are, as shown in the table, related in the fourth degree; there being one degree of ascent to the father, and another to the common ancestor, the grandfather; and from him one of descent to the uncle, and another to the cousin-german, making in all four degrees.
  (ii) A grandson of the brother and a son of the uncle, i.e., a great-nephew and a cousin-german, are in equal degree, being each four degrees removed.
  (iii) A grandson of a cousin-german is in the same degree as the grandson of a great-uncle, for they are both in the sixth degree of kindred.
