You're in luck. I have not done any research since 2007 but I was doing a google search and came across your question. I did research into Safron Kulba. I have all my research at home right now but you can contact me if you're still doing reseach in this area. If my memory serves, he was married to my grandmother's sister. I have the exact info at home, that I would be glad to scan and send you. I also have lots of info on Bila, Chortkiv and the Kulba name from that area.
