Meaning:
Its source is margaron, a Greek name meaning "Pearl."
Narrative:
This name came into use among English speakers by way of Latin (as Margarita) and Old French (as Marguerite). It has been closely identified with Scotland, to the point that one commentator has pronounced it ''the national Scottish female name.''
However, in the late 20th century it has been most prominently borne by Englishwoman Margaret Thatcher, the United Kingdom's first female Prime Minister.
