Gregson is of English origin, derived from the Old French word 'Gros', meaning 'large'. It was originally used as a nickname for someone of considerable size, either physically large or having a large nature, such as being generous-hearted or boisterous. The name Gregson has been traditionally associated with northern England, particularly in areas where the Normans settled after the Norman Conquest in 1066.
"Only ten babies named Gregson have been born in over five decades."
