Hello Ingrid,
Have you already seen this obituary/biography for Clarence Boyer,
who looks like he might have been married to your grandmother?
www.americanboyers.org/newsletters/2003news.pdf
According to this, his second marriage was "1947, Berlin, Germany,
to the Countess Eugenie von Liedert, who died Aug. 27, 1972. She
resided at Staunton, Va. Violin virtuoso and orchestra leader,
dau. of Count Robert von Liedert, St. Petersburg, Russia."
If true, it might be a Baltic noble family (but I confess,
I do always wonder a bit about family stories with a von X ancestor)
