Regarding Netta...she travelled to Boston I think, arriving in 30 Dec 1912 on the 'Sicilian', from Glasgow. Mother given as Mary, living at 42 Garden Street, Kirkwall, Orkney.
Maybe/likely 1901 census is wrong. Mary was Elizabeth/Betty's mum

NOT sure on connections overall really so far...
Second page to this manifest. Mentions an Alec Learmonth I think. A bit jumbled that section.
