You're welcome.

The CZ's atlas that I have from 1996 only shows this 2 Borovices just like this site:
Borovice, Worowitz populated place 49°34' N 12°56' E E M U G Czech Republic 77.1 miles WSW of Praha 50°5' N 14°28' E
http://atlas.mapquest.com/maps/map.adp?searchtype=address&am... This village is closer to Germany...
Borovice populated place 50°15' N 15°59' E E M U G Czech Republic 68.1 miles E of Praha 50°5' N 14°28' E
http://atlas.mapquest.com/maps/map.adp?searchtype=address&am... Not close to Poland's border.
No village Borovice show up in http://www.zanikleobce.cz/
[no longer in existance villages] site so I wonder too where you find Borovice that are close to Poland's border.
In CZ: Borova, Borovany, Borovec, Borovice, Borovicky, Borovinka, Borovka, Borovna, Borovnice, Borovnicka, Borovnik, Borovno, Borovsko, and Borovy. No Borovica.
