The name came from the state of kintuckye

Since you asked for meaning in czech (and polish - slavic languages) context 

I will focus on commenters guess of 

"Czech: from a pet form of the personal names Boleslav or Bolebor "

 Bole-Slav means 'more glorious' 

Bole has same root as russian (slavic language) Bolshe (which is found in
the popular party label 'Bolshevik' (which I should add Lenin adopted in one
 rare moment in which his faction got a majority in some vote.

Slav is second part of at least third of first names, names which
celebrate (gloryfy) everything, form spring, to peace, rule .. or just
have 'more glory'
as Boleslav (and a similar meaning) Wencse-slav (famous king from a Xmass carol)
where (interestigly) Wence comes from 'více' which also means 'more'

Hi,

I found this information from ancestry.com

Czech: from a pet form of the personal names Boleslav or Bolebor. 

Polish (Bole?): from a pet form of the personal name Boles?aw. 

Variant spelling of German Bohlen. 
Swedish (Bolén): ornamental name composed of an unexplained first
element + the common surname suffix -én, a derivative of Latin -enius
?descendant of?.
 
English: variant of Bullen. 

Digging a little deeper to the name Bullen, the same site provided the
following information

English: habitational name from the French Channel port of Boulogne,
recorded in Latin sources both as Gessoriacum and as Bononia. The
latter name is clearly the source of the modern place name. It is
ostensibly a derivative of Latin bonus ?good? (compare Bolognese), but
may in fact come from a Gaulish element bona ?foundation?. Boulogne
has long been a major trading port between England and France.

And for Bohlen:

German: patronymic from Bohl 1. 
German: habitational name from a place in Westphalia named Bohlen. 
German (Böhlen): habitational name from any of several places in
Saxony named Böhlen.
Swedish (Bohlén): ornamental name from Bohl 1 + the suffix -én, a
derivative of Latin -enius ?descendant of?.

Hope this helps.
Simon.
