Islington

(N1) Called also Iseldon, Yseldon, Eyseldon, Isendune, and Isondon. It was once as famous for its cheese-cakes as Chelsea for its buns; and among its other notabilities were custards and stewed "pruans," its mineral spa and its ducking-ponds-Ball's Pond dating from the time of Charles I.
