Livermore
English: probably a habitational name from Livermere in Suffolk. This is first found in the form Leuuremer (c.1050), which suggests derivation from Old English lefer ‘rush’, ‘reed’ + mere ‘lake’. However, later forms consistently show i in the first syllable, suggesting Old English lifer ‘liver’, referring either to the shape of the pond or to the coagulation of the water.

'the pond' above I assume is referring to Ampton Water, which does have an odd shape.

>>>A miserable bunch of puritans - no singing, dancing, wearing nice bright clothes, dour, God-fearing, witch-burning, po-faced party-pooping stuck-in-the-muds. And their decendants haven't changed much! {GR&R}
