What stands out about Severna Park’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The name Severna Park is rumored to originate from a 1906 contest held by Oscar Hatton while the modern community was first becoming established. The winner would receive a portion of land but controversy arose because the winner was an African-American woman, who was instead rewarded $500. However, extensive research by local historian Nelson Molter found no corroborative evidence for this story, suggesting the naming contest is merely a local myth.
