First found in West Prussia and Pomerelia, where the name emerged in mediaeval times as one of the notable families in the western region. From the 13th century onwards the surname was identified with the great social and economic evolution which made this territory a landmark contributor to the development of the nation. Early records show a Chuonrad Rufus faber qui dicitur Slosser in 1290, in records relating to Basel; and he is recorded again in 1294 as Cuonrad dictus Slosser.

Some of the first settlers of this family name or some of its variants were: John Jacob Slusher, who came to Belize in 1792; S. Slusher, who settled in San Francisco in 1852; Philip Slusher, who arrived in Indiana sometime between 1852 and 1861.
