As far as I know, there are only two sites in the blogosphere that currently focus on Croatian genealogy in the English language: 100 Years in America and Ćurković.ca.
I have been a fan of Ivan Ćurković's blog since I discovered it over a year ago. It is nice to have a fellow blogger writing about the world of my ancestors, even though we do not share a family connection and we are usually focusing on different regional areas.
As a son of Croatian immigrants living in Canada, Ivan has connections to family back in Europe that many of those researching their ancestors may not have. He also has something that I wish I could share: a proficiency with the Croatian language!
Ivan has traced his Croatian ancestors back nine generations (that's 300 years) to an area of what is now Bosnia-Hercegovina called Buško Blato and maintains a website about the genealogy of families from the area at BuškoBlato.org.
Ivan has recently put together a series of articles that have very helpful tips for those getting started and/or wanting to make further progress on researching their Croatian roots. At this point, he has three installments in his series. I'm looking forward to more in the future! Here are parts one, two and three:
