Anybody ever heard of this Alexander SIM, born about 1820 at Lambeth, Middx, England? He married Agnes (surname unknown) (born about 1827, Hornsey, London)and had at least a son Stewart, according to a Will dated 14 January 1881, and Alexander and Agnes were staying at the Gorsvenor Hotel in London on Census day, 1881. My distant kinsman, he of the Will, claimed Alexander & Agnes as his cousins, but the surname SIM is unknown in our family tree . . .
