I know very little about the Drotars. My husband's family knows very little to tell me to go on. I would be VERY interested in ANY Drotar info you uncover. I believe that all the Drotars are related. It is such an unusual name and there are very few people doing research on it. Send me your e-mail address to gdrotar@midsouth.rr.com and I will forward to you what I do have in my Drotar file. I look forward to hearing from you!
