I've noticed that someone with non-White/Aryan ancestry usually starts showing it in their senior years. That's when the "jewy" part comes out in force.
It happens to those with partial oriental ancestry; that singer/vocalist with the stage name Saffron in the 1990s music group Repulica. She looked quite White in the 1990s but nowadays is showing some old oriental woman visage.
It happens to those with partial negro DNA; Jayne Kennedy from the 1970s She is seriously looking full negress nowadays.
I've seen some red indians who looked White as youths and then late in life started getting the Sitting Bull look to them.
Hell, even Joseph Goebbels looked later in life like he had some serious Mediterranean ancestry. Looked like a German in young life, but started getting that "Guido" look, like some Mafia crime boss appearance to him.
It also happens to jews. Some jews when young look Aryan, even with blonde hair and blue eyes, but the jewy part comes out, like others, in the senior years. Even that abhorrent Ruth Bader Ginsburg in her youth didn't seem to have any jew to her. But now? Holy Hebes! Poster girl for jew wench/witch.
So, if you want to know the ancestry of who you plan to marry, or you want to know the same for your kids/descendants, then find any/all photos of that marriage prospect's direct family members in their senior years. As far back as possible. Because it, non-White ancestry, will most likely show up in those senior years.
