Hello, all you Pirc-Searcher out there,
I am sitting here in Ljubljana, Slowenia, and do microfilming (for the Genealocical Society of Utah)the "Popis prebivalstva", which means counting the population, wich they did about every ten years in the past, and there is no day, without seing a Pirc on the documents. So, if you go to the site of the "Church of Jesus Christ of Latter-day Saints" www.lds.org
, and then from there to Family History and so on, you find your way to the place search and find out, what has been filmed for Ljubljana. I am not finished by far, but am here over half a year, so maybe some films are allready available for you to look at in your next Genealogical Library of the Church in your area.
Also often I see "Vidmar", but very often "Supan (or Zupan)" and their variations.
Good luck and Gods blessings to you in your searching.
