User blog comment:La-Artist322/Isn't she part of the Reiss family as well?/@comment-38964308-20201007152757

Initially, she was a maid in the Reiss household and the mistress of Rod Reiss, when she was pregnant and mother of an illegitimate child, she was obviously sent away in her parents farm, of course,she and Historia were denied from any affiliation to the royal family,and Historia initially have no right to claim the royal throne because she is illegitimate in the first place, however, her status was used by the millitary to appoint a new figurehead instead of the fake king.

Alma was not Rod's wife in the first place, and because she bore his child, she was probably given an estate and a small allowance, but that was probably not enough for her living expenses, so that forced her to work as a escort girl.

In history, illegitimate children and the royal favorites are not always powerful in political realm, there are countless examples of Kings who get rid from their mistress and their illegitimate children, and even if the illegitimate children are entrusted with power, it's because they potentially do not exerce a threat for claiming royalty or in a few exeptions, they are granted the throne in extraordinary and special circumstances (civil war-absence of heirs-they have a minimum of political influence,used as last legitimacy resort like Historia.)

It's totally different from the Yeager family, because Dina was turned into a titan, so she lost every human connexion with Grisha, who in the same time, started a different family in the Walls when no one knows about his past in Marley or his first marriage.
