Olive tree; ancestor's descendant
Olly is primarily a diminutive of Oliver, which stems from the Latin word for the olive tree, a symbol of peace. It is also linked to the Old Norse name Olaf, meaning ancestor's descendant. While historically a nickname, it is increasingly used as a standalone name in the UK, though it remains rare in the US.
