My husband's, Louis, birth mother was Anna Zak, who lived at 1064 Finley Ave in Manhattan. She was from Hungaria. She was 22 in 1920 so she was probably born in 1898. The father was William Schreif also from Hungaria. He was 25 at the time of Louis's birth. He would like to know if he has any brother or sisters out there. WE just found his first birth certificate. Any help would be greatly appreciated.
