My wife is a Jirava from a small Mn town. Her dad is Jerome (Bud) the youngest of 4(1 died in infancy) b 1922. In about 1968-69 Vrativslav, Aloise, Ladislav were here in Mn. Bud & his wife went to Czechoslovokia around that time too to visit.
Bud is now the sole surviving brother. There was a Vondra in a small nearby town some years ago.
