Hello Ell, yes!!!!That sounds like the people I am looking for.
I found in the meantime:

Helene Kaune crossed the border from Canada to the US on 4.6.1947. I have no idea what she was doing in Canada.
Anyway, seems she had two daughters,
1. Dena Heyer, nee Kaune
2. Wilhelmine Burg, nee Kaune, b 10.10.1902, d Apr. 1996 in Putnam NY

Wilhelmine Burg also had a daughter,
Helene Wilhelmine Burg, b 6.9.1923, d 10.4.2009 in Palm Desert, Riverside, California

Well, bit by bit this is coming together.
Thanks!
