Might I suggest your also checking a similar name, in my wife's
family; FUCHSBERG? Or to put it more broadly, you might need to
check more than just the exact spelling of FUCHSBALG (if that's
what you've been doing).

Best of luck,

My great-great-grandmother's maiden name was Rosalia FUCHSBALG; she
was born in Rzeszow, Galicia. FUCHSBALG is not a common name. I have
not had any success in researching her ancestry....
