She had some other relationships that may be more significant.
She was the mother of Joseph Tontonghi who ran the boarding house where Anna purportedly lived--why haven't we heard from Joseph about the events of 1960-61?
She was also the aunt (sister of Alexander Sarruf, father of Nadia who was the mother of Chantel Anderson) of the woman whose husband wrote the first article in Seattle Weekly attempting to convert Anna to Stanley; in which article he attests that no child accompanied Anna to Seattle to live in the boarding house.
(Point of that is that you are supposed to believe that Stanley was the mother on August 4; abandoned the kid with its father a month later; didn't see him again until some date later than 1962; and then sent him to Indonesia in early 63, around six months later, where she didn't see him again until sometime after 1966 according to Lia, the housegirl.)
And, Lorice, as you say, first cousin to Faud, is first cousin once removed to Faud's daughter Valerie; and is thus first counsin twice removed to Fauds grandson by daughter Valerie and we all know who he is.
What an incredibly strange web of connected people.
Look at this, I found an image of that Valerie, she played a part in a TV series named The Avengers in the UK in an episode from the 1962-1963 series:
The part she apparently played was Anna Rosas. If you click on that name on the page, it shows the photograph.
