How did Queen Mary effect American history?

You have to be a bit more specific, there are several "Queen Marys" did you mean Mary I of England who ruled from 1516-1558, Mary Queen of Scots who ruled Scotland from 1542-1587 or did you mean Mary II of England who ruled from 1662-1694? Without knowing which of the 3 "Queen Marys" you want, it is impossible to answer your question.
