I know this reply comes 5 years later, but hey, it's worth a shot.I'm actually curious about whatever info either of you have.The reason I'm particularly interested is that my family is full of both musicians and teachers; could be a coincidence, but that is also what Leos Janacek was known for.
My 3x great-grandmother's maiden name was Janacek (First name Barbora/Barbra), and though I cannot find records on where exactly in Czechoslovakia she came from, she did speak Czech.She was born circa 1839, and married Mikel Cabak before coming to the US in 1884.She and Mikel had two children before coming to the US--Mikel and Celestyna (sometimes called Mary).
They settled in Kansas.I know they spoke Czech, as Celestyna married Antone Tomanek, who was from Svinov (in Silesia/Moravia), and he spoke Czech.Mikel married Anna Marek and moved to Minnesota.
Barbora never mentions anything more than that she was from Austria, and that her parents were from Austria.She died in 1902.I have tons of information on her descendents (I'm from Celestyna's line) if that applies to anyone.
The family story is that the Cabaks were purposefully vague about their past because they were gypsies and didn't want anyone to know it.Of course, this is probably just a story, but I have yet to verify one way or the other.
