During the Commonwealth, William Darwin became a barrister of Lincoln's Inn, and this circumstance probably led to his marriage with the daughter of Erasmus Earle, serjeant-at-law; hence his great-grandson, Erasmus Darwin, the Poet, derived his Christian name. He ultimately became Recorder of the city of Lincoln. The eldest son of the Recorder, again called William, was born in 1655, and married the heiress of Robert Waring, a member of a good Staffordshire family. This lady inherited from the family of Lassells, or Lascelles, the manor and hall of Elston, near Newark, which has remained ever since in the family. (Captain Lassells, or Lascelles, of Elston was military secretary to Monk, Duke of Albemarle, during the Civil Wars. A large volume of account books, countersigned in many places by Monk, are now in the possession of my cousin Francis Darwin. The accounts might possibly prove of interest to the antiquarian or historian. A portrait of Captain Lassells in armour, although used at one time as an archery-target by some small boys of our name, was not irretrievably ruined.) A portrait of this William Darwin at Elston shows him as a good-looking young man in a full-bottomed wig. This third William had two sons, William, and Robert who was educated as a barrister. The Cleatham property was left to William, but on the termination of his line in daughters reverted to the younger brother, who had received Elston. On his mother's death Robert gave up his profession and resided ever afterwards at Elston Hall. Of this Robert, Charles Darwin writes (What follows is quoted from Charles Darwin's biography of his grandfather, forming the preliminary notice to Ernst Krause's interesting essay, 'Erasmus Darwin,' London, 1879, page 4.):-- "He seems to have had some taste for science, for he was an early member of the well-known Spalding Club; and the celebrated antiquary Dr. Stukeley, in 'An Account of the almost entire Sceleton of a large Animal,' etc., published in the 'Philosophical Transactions,' April and May 1719, begins the paper as follows: 'Having an account from my friend Robert Darwin, Esq., of Lincoln's Inn, a person of curiosity, of a human sceleton impressed in stone, found lately by the rector of Elston,' etc. Stukeley then speaks of it as a great rarity, 'the like whereof has not been observed before in this island to my knowledge.' Judging from a sort of litany written by Robert, and handed down in the family, he was a strong advocate of temperance, which his son ever afterwards so strongly advocated:-- From a morning that doth shine, From a boy that drinketh wine, From a wife that talketh Latine, Good Lord deliver me!
