You are my fairy godmother! I just can't believe how this may be coming together with your help.
From what I could tell on the baptismal record, the mother's first name was Katerina. The ship's manifest shows that Ludmila and Maria were going to a brother-in-law whose last name was Cerny. However, Cyril remembers his mother saying that they were going to an aunt in Chicago. The Ptacek name may actually be on the birth/baptismal record, but, like I'v said, I can't quite make it out. I will try to get it to you later today.
THANK YOU!!!!!
