Sheldon

English: habitational name from any of the various places so called. The main source is probably the one in Derbyshire, recorded in Domesday Book as Scelhadun, formed by the addition of the Old English distinguishing term scylf ‘shelf’ to the place name Haddon (from Old English hǣð ‘heath(er)’ + dūn ‘hill’). There are also places called Sheldon in Devon (from Old English scylf ‘shelf’ + denu ‘valley’) and Birmingham (from Old English scylf + dūn ‘hill’).
