Firmstone Family History
Firmstone Surname Meaning
English (West Midlands): most probably from Middle English firme son ‘first-born son’ with intrusive -t- due to the influence of habitational names ending in -ton. Early examples such as John Furmson (1664 in Ellesmere Shropshire) support this hypothesis.
Origin as a habitational name from Furmiston in Dumfriesshire Scotland is also possible but no early examples in Scotland have been found.
