Hallum Name Meaning, Origin and Heraldry
Hallum is best understood together with Hallam: both are English spellings of a single family name. The name is usually explained as “Someone who came from Hallam or Halam (corner or remote valley)”. Before spelling was fixed, Hallam was also written Hallum.
According to the 2010 US Census, the Hallum surname had 1,782 bearers. That puts it among the top 25,000 US surnames.
A coat of arms belongs to a particular family line rather than to everyone named Hallum, so the heraldry linked to Hallam is a starting point, not an automatic right. Want more than a summary? See the Hallum family name pack.
