Ilava (or Illava), is a town in Trencin area.
Records >from this town exist, >from as early as 1800,
and these were filmed by the FHL.
However, record images are not (yet) accessible on familysearch.org
The BMD are available on the JewishGen All-Hungary Database.
If anyone has copies or scans of Ilava records, >from before 1870,
I would be interested to take a look at it
If anyone can help - Please contact me privately
