This is because the nature of the Morrígan is highly confusing and somewhat disputed amongst those into Celtic mythos. The Morrígan is generally regarded as a triple goddess, meaning she has three distinct aspects, usually Macha, Badb and Nemain. So if one source refers to Badb/Nemain and another refers to Morrigan, they are likely still talking about the same deity.

There was a legend called the Children of Lir, in it Aoiffe, daughter of King Badb turned the children of her husband's first wife (and her sister) into swans, and in exchange she was turned into an Air Demon. So, at least mythologically there was.

Social rank and occupation played a significant role in the growing democratization of American politics. The development of a more inclusive democracy in the early 19th century gave greater political influence to those outside the traditional elite class. The expansion of voting rights to white men of all social ranks, regardless of property ownership, allowed ordinary citizens, including those in different occupations, to participate more actively in the political process. This led to a more diverse and representative political system.

Often represented by hounds or, more commonly, the raven. Her three aspects are usually given as Badb, Nemain and Macha or Fea (Macha is often considered a separate goddess, patroness of battles.)
