It probably isn't present in the Czech Republic anymore (it isn't in the statistic of the Ministry of Inner Affairs available on its web), but Jim Young should be right - "burg graf" is often turned into Czech as "purkrabe" and I have a feeling some dialects tend to turn it into "pulkrabe". So that's where it comes from - Czech version of German word(s).
