Sowerbutts Family History
Sowerbutts Name Meaning
probably from the lost place-name Sourbut in Garstang (Lancs) with excrescent -s. The place-name appears to derive from Middle English sour ‘mud mire slime’ (Old Scandinavian saurr ‘mud dirt sour ground’) + butte ‘strip of land abutting on a boundary small strip of land’.
