Could also be a nickname for "Ermin-" names such as Ermintrude, Ermingarde, and Erminberga. Minnie as a nickname for Jasmine seems pretty... weird to me. Minnie is such an old fashioned name (not that it's a bad thing), while Jasmine is such a modern one.
In 2018, 83 is the most common age for an American (U.S.) Minnie who is registered female with the Social Security Administration. It is the 833rd most common female first name for living U.S. citizens.
