My sincere thanks to all those who responded to my question about
Petrisorul, all of your comments were very helpful.
Some referred me to the JewishGen Gazetteer (which of course I
should have consulted first), which said the Petrisorul is now
Lunca Petrisorului. Other Internet sources equated Petrisorul
with present day Petrisoru. Actually, these two villages are less
than two miles apart.
Thanks again to you all.
