Sorry, her parents were Getzel Hecht and Celia Gruner. I'm very excited to find them after 6 years of exhausting research!
I only tryed another spelling of my grandfather given name, Mardoqueo, and the first link Google showed me was his temporary visa to Brazil!
His cousin was Mendel Gruner, my mothers name is Celia, it can't be a coincidence. The date of birth is the same I knew.
I'm very excited, even though all my ancestries used to catch from us their past I'm succedding not bad, at the Russian branch too :)
