I saw a fan made family tree imagining links tying characters togather. A lot of it I didn't care for as it involved nearly every woman having a secret illigitimate child. It was just too much to accept that Millicent, Abigail, Natalie and Edith all had a secret illigiitmate child, even in fan fiction, Kitty and Rachel were twins, etc.
This family tree did have Magda as a descendent of Natalie, and that Magda and Sandor had a child not mentioned on screen, who was the grandparent of Julia. I do kind of like the idea of Julia being the great granddaughter of Magda, and it's not too hard to believe that Magda could've had an adult child who was still traveling with the other gypsys.
I did like Magda's gruff affection for Sandor, one of the best couples on DS.
