HL is one of the oddest consonant clusters to start any name or word with; hlots of us hlive with it.
Hlands

There's only a few hlands and hlanguages with the HL
thing.  Here they are presented in order of the frequency.  
Czech wins, with South Africa a close runner up.  Then,
following them are Slovakia, Zimbabwe, Slovenia, Serbia,
and so on.   

These are the flags of the people and countries whom join
in HLness.  They are the starting point of all things HL.  By
clicking on a flag you will learn more about the HLness by
which these countries live.

Or you'll find the information inadequate and email me
more details and better information.

Hlidas na Praze.  You are looking at Prague.  
To je
Hlavni mesto ceskem.  It is the capital of the Czechs
(and you're reading the caption with two HL words - yah!)
     There are some 8,000 known languages on earth.
Strewn throughout them are every single possible
sound capable by the human tongue.  Some sounds
are so universal that they appear in every language.  
Other sounds are found in thousands of languages,
approaching universality.  Still more hundreds of
languages share sounds.  There are languages that
are exceptions because they are without the sound
shared by so many.  It would surely be an intriguing, if
bizarre, list of the sounds that are so unique that they
are found in few languages.  Some sounds, like
English's TH combination are actually unique to a
language and are found in no other.  

    And so it happens that HL as a consonant cluster is
found among a minuscule number of languages.  In
fact, one can pinpoint pretty much that it is between 14
and 25 languages. No less than the languages of the
14 countries to the right.  In Burma and Laos, often the
HL is actually found in the Hmong hlanguage, but these
people do not have their own country, and they are
closely identified with the two countries.

    It is upwards of 25 because there are apparently
some dying or even extinct North American Native
hlanguages, particularly in the Artic Region, with HL.  
Given the HL remnants found in a few place names
along the frozen shores of the Artic Ocean the sound
was most likely more prevalent in words, names and
places.   There is also the remnants of the Hlai people
and hlanguage of Hainan, a unique province of China
on a large island off the coast.
