Hello,
All of the messages about the Leksa name are fairly old, but I just came upon them today. There is a website that gives the frequency of Czech names at the present time and the area where there is currently the highest concentration is Policka, Litomysl and Svitavy which are all in East Bohemia. I know the name from the village of Teleci which is close to Policka. A Leksa family bought Teleci #78, which is where my great grandfather Josef Rousar lived as a child. One of the posts refers to both the names Rousar and Leksa from Cedar Rapids so it is possible they came from this village or one close by.
