Rodman
A surname usually explained as a variant of Redman, though in some cases it may also reflect an older Germanic name element like Rod- seen in Roderick or Rodger.
The #6,134 most common surname in the United States (2010 Census) — about 1 in every 55,281 Americans shares it.
Etymology
Most early surname books treat Rodman as a variant of Redman, usually understood as a descriptive nickname for someone with red hair or a ruddy complexion. That is the simplest reading of the name in English contexts, and it fits the way the spelling could shift over time. Harrison, however, notes an older Germanic possibility: in some very early records the first element may be the same one found in names like Roderick and Rodger, built on a root meaning 'fame' or 'renown.'
History
The name is recorded in medieval English sources and later appears in parish and civil records in several English counties. By the 18th and 19th centuries it was established enough to show up in London and American records, which matches the broader spread of many English surnames. Some historians have also connected it with Rodman-like spellings in continental German records, though that line is less certain.

Fun fact
One 19th-century surname dictionary even points out that Rodman may simply be a spelling variant of Redman, showing how fluid surname forms could be before modern standardization.
