Meaning and background
The story behind Jeffrey
Jeffrey is documented as a medieval variant of Geoffrey. The main name reference also distinguishes its usage pattern in America from Britain, showing that related spellings need not have the same history of popularity. That is more specific than assigning Jeffrey a new literal meaning. A dog named after a person can preserve the exact form used by that namesake, while any deeper derivation should follow the linked Geoffrey history.
