In the 1930 census I show a Sylvesta and Ethel Kokai living with the Kiszeli family as Brother in law and sister in law to Vincent Kiszeli. I am trying to figure out who they are. Vincent and Katherine are my husband's great grandparents. They are also living with their daughter and her husband John and Margaret Mully. I would love to find out any info on any part of this family. It is possible that the Kokai family could be from the Meszaros family which is Katalin or Katherine's maiden name. They all came here from Hungary. Kokai is listed as coming to the USA in 1920.
