One of my favourites is the Oxford History site, which has pages featuring some of Oxford's most famous and historic streets, and much more besides. There are also sections on Headington and Marston, and old picture postcards of villages all over Oxfordshire. So if you have Oxfordshire ancestors you are sure to find something to interest you.
The photographer Henry Taunt 1842-1922 at various times occupied premises in three of the the streets featured in Oxford History; Broad Street, Cornmarket Street and High Street (also called 'The High'). In the Footsteps of Henry Taunt is devoted to his photographs of Oxfordshire and the Thames, including locations in Berkshire, Surrey, London and Middlesex.
If your Oxfordshire ancestors were among the great and good, or if you just want to know if anyone famous ever lived in their street, the Oxfordshire Blue Plaque site is worth a look.
