Fyrer
Fyrer is an English-language word and surname with historical and occupational associations connected to fire. As a common noun, it has been used as an agent form denoting a person who tends, kindles, or maintains a fire — for example in domestic hearths, industrial furnaces, or marine and locomotive boilers. In some historical sources and dialects the spelling fyrer appears as a variant of firer or fireman.
Etymology traces the element fyrer to Old English fyr, meaning "fire," combined with the agentive suffix -er.
In modern English the form firer or fireman is considerably more common; fyrer is now largely archaic
