Omdahl is a Norwegian surname derived from the name of farms in Norway.EtymologyThe name Omdahl originates from several homesteads in the regions of Agder and Rogaland. The farm names Åmdal or Omdal combine the Old Norse element ár (meaning “elm”) with dalr (“valley”), thus signifying “elm valley”. The surname therefore identifies someone who hailed from such a valley.DistributionAs a Norwegian surname, Omdahl is most common in Norway, but due to emigration, it is also found among Norwegian-American families.Notable BearersDavid Omdahl (born 1956), American politicianHarmon T.
