Question: When does the younger son of Jacqueline Frances Stallone born?
Context: A secundogeniture (from Latin: "secundus" "following, second," and "genitus" "born") was a dependent territory given to a younger son of a princely house and his descendants, creating a cadet branch.  This was a special form of inheritance in which the second and younger son received more possessions and prestige than the apanage which was usual in principalities practising primogeniture.  It avoided the generational division of the estate to the extent that occurred under gavelkind, and at the same time gave younger branches a stake in the stability of the house. The Biddulph Baronetcy, of Westcombe in the County of Kent, is a title in the Baronetage of England.  It was created on 2 November 1664 for Theophilus Biddulph, of Westcombe Park, Greenwich, Kent, Member of Parliament for the City of London and Lichfield.  His son, Michael, the second Baronet, also represented Lichfield in the House of Commons.

The late Baronet was succeeded by his first cousin once removed and namesake, Theophilus, the fourth Baronet.  He was the son of Edward Biddulph, elder son of Simon Biddulph, younger son of the first Baronet.  His grandson, Theophilus, the sixth Baronet, fought in the Battle of Waterloo and served as High Sheriff of Warwickshire in 1849.  He was succeeded by his son, Theophilus, the seventh Baronet.  He was a Deputy Lieutenant and Justice of the Peace for Warwickshire.  On the death of his son, Theophilus, the eighth Baronet, in 1948, the line of Edward, elder son of Simon Biddulph, younger son of the first Baronet, failed.  The late Baronet was succeeded by his fourth cousin once removed, Francis, the ninth Baronet.  He was the great-great-grandson of Walter Biddulph, younger son of Simon Biddulph.  As of 2008 the title is held by his grandson, Jack, the eleventh Baronet, who succeeded his father in 1986.  The three most recent baronets have resided in Australia.
