Misha, I hope this message finds you through the internet. Sorry I didn't reply sooner. We had an influx of Solarov's in the early 1900s from the part of Serbia you mention, Kesca or Klari Banat, which seems to be in the area you mention. I feel that these Solarov's were related to the people in the Banat area of Jugoslavia, but am unsure how to go about researching farther back. Was the area torn apart by war or were the churches left alone? (records of births, deaths, marriages should be found there)...
