William Robins (c.1731-1762) and Martha Hall had three children baptised at St Marys in Portsea, and Martha, the daughter of Samuel Hall, was also baptised at St Marys (6 June 1736). Samuel Hall Robins moved to London where he married Lucy Godsoe on 1 September 1782, while William Robins remained in Portsea where he married Mary Cornthwaite Temple on 7 September 1781 at St Marys and was buried on 1 April 1810, again at St Marys in Portsea.
William Robins, despite being "in perfect health", died within two months of writing his will. His uncle William Robins Esq (buried at Malmesbury, 11 February 1760) had bequeathed him considerable property in Cromhall, which he left to his wife Martha to hold for his son William until he turned 21. However, due to the nefarious dealings of Richard Matthews (who married Ann Jack, the niece of William of Cromhall) and Conway Whitehouse (an unscrupulous lawyer who obtained and disposed of the estate), I doubt that young William Robins actually inherited any property in Cromhall.
William Robins of Cromhall gave and devised his properties to his wife Ann to hold until her decease, when his capital messuage and residence in Cromhall with all houses etc. should have passed to his nephew William and his heirs. Ann Robins was buried at Cromhall on 4 November 1781 and the only living trustee and executor of her will (Francis Jobbins) refused to act in proving the will or in his executorship.
If the William Robins who married Hannah Hale in 1771 was from Portsea then he was only 16 years old, with a long wait before the possibility of any inheritance in Cromhall, and if he died in December 1775 it was tragically just before his 21st birthday. But if William married Mary Cornthwaite in September 1781 he was 26 years old, perhaps aware that Ann was infirm and expecting his inheritance within weeks.
