Here are the results of a search for the Palčič surname:
I’d like to see the statistics for the regions where the data is not available, but it’s clear that Palčič is not a common surname in Slovenia. For comparison, here is a table taken from the results of a search at http://forebears.io:
The data from the two different sources is not exactly correlated, since the Slovenian set was created in 2016 and the Forebears data was created in 2014. Additionally, the 2016 data from Slovenia probably excludes a number of instances from the statistical regions where the data are confidential. I also have a data set from US telephone directory listings that includes variant spellings not shown in either of the lists above.
I’m experimenting with Tableau® software and the data I’ve collected for Palcic immigrants from Slovenia and Croatia who left those countries for destinations in the United States. I hope to create some interesting visual displays for various data sets over the years that Palcic individuals or families arrived in the US.
