In the settlement of the estate the heir-at-law (inheritor of the real estate) was declared to be George Augustus William Curzon, a descendant of Robert Jennens' eldest sister Hester. His mother Sophia Charlotte Howe (Baroness Howe and Lady Curzon) took possession in behalf of her second son, Richard William Penn Curzon (1796-1870), who was created first Earl Howe in 1821. Earl Howe was later alleged to have been an illegitimate son of a spinster named Ann Oakes, substituted as the heir-at-law.
The personal property of William Jennings was divided between the living next-of-kin who were William Lygon, first Earl Beauchamp (1747-1816), a grandson of Hester Jennens, and Mary, Lady Andover, a granddaughter of Humphrey Jennens' daughter Ann. 30
The claims of American descendants of William Jennings, uncle of intestate William Jennings, are based on the fact that children of the uncle were alive in America at the time of the intestate's death and should have been considered as next-of-kin with Lady Mary Andover and Earl Beauchamp. Furthermore, if the alleged illegitimacy of the first Earl Howe could be proven, the question of proper disposition of the realty would likewise entitle the American claimants to consideration. The matter is further complicated by the fact that parish church at Nether Whiteacre, eldest son of Humphrey Jennens, died unmarried, willing his real estate and his rights in entailed property to the heirs of his sister Hester. 31
