What is "larkman"

Larkman is an Anglo Saxon surname used in the UK, United States, Australia, New Zealand and Canada. Although Larkman is a very uncommon name it is not historically rare in Norfolk, England and it is possible that all Larkmans originated from Norfolk. Research carried out by Frank Randall and Brian Larkman has revealed that only a handful of Larkmans can be found outside Norfolk and Suffolk before 1800.
