Re the question what was happening in Western or Central Europe in the early 70's? I need to check that one, first what comes to mind is the oil crisis in '73, and also a lot of migrants entered Western Europe from Italy, Spain, Turkey since the '60's to work here.
If she was from Western or Central Europe, I wonder why she moved to PA. I mean Pennsylvania is not what first comes to mind if I would move to the US,
so was it a boyfriend, parents that moved, did she have relatives who already lived there, or was she an au pair, or was she offered any other job there or something? She must have known people who lived there.
