Hello Dave, Sari had a brother Stephan. Sari's frather was Dr. Stephan. I'm trying to find out if my great grandfather Janos was Dr. Fedak's brother. The only bonafide relative of Sari's I found was Maria De Day nee Fedak from Argintina. Sari was her aunt and Steve was her father. I don't know if she is still around but it was difficult to communicate with her by email. I suspect that she didn't get most of my messages as she lived in Caracus.
