Salzman/Saltzman (salt merchant)
Salt, Salter, Sulter, Saltman and Salterman, this is an English surname of two possible origins. The first is occupational and describes an extractor or seller of salt, the derivation being from the Olde English pre 7th century world "sealt" meaning salt. The surname from this source is first recorded towards the middle of the 13th century (see below), and Thomas le Selter appears in the Subsidy Rolls of Sussex in 1296, whilst John Saltman is recorded in the Pipe Rolls of Suffolk in 1327. The second distinct possibility is that the name derives from the pre 7th century Olde French words "saltere or sautere", meaning a psalter.
Waller may also be an occupational name for someone who boiled sea water to extract the salt, from the Middle English well(en), meaning "to boil."
