Scottish (Lanarkshire) and English: patronymic from the Middle English and Older Scots personal name Sim(m), Sime (see Sim ) + -son.
English: occasionally a variant of Sumsion with unrounding of the vowel before the nasal consonant, a dialect feature of southwestern England.
English: habitational name from any of the three places called Simpson or one called Zemson, all in Devon. The one in Holsworthy parish derives from an uncertain first element + Old English tūn ‘farmstead, estate’, while the one in Diptford comes from the Old English personal name Sigewine (genitive Sigewines) + Old English tūn. Both the one in Torbryan and Zempson in Dean Prior probably also have the same origin as the Diptford placename.
