Haldor is a Scandinavian given name derived from Old Norse elements 'hálr', meaning 'neck' or 'collar', and 'thórr', the name of the thunder god in Norse mythology. The name was popular among the Vikings, who likely associated it with strength and power due to its connection to Thor. In modern times, Haldor is still used as a given name in Scandinavian countries, but it remains relatively rare outside of these regions.
"The name Haldor was quite popular between 1916 and 1925, with the most notable years being 1924 and 1925 when it saw six and seven births respectively. In total, there were eighteen children named Haldor born during this period."
