Are you sure that they married in 1919?There's a WV marriage index listing for a Frank BARATH to a Helen HAGDU in 1926 in Logan Co, WV.
According to Frank's WWII draft registration, he was born 10 Sept-1888 in Czab, Redek, Hungary.
According to the 1930 census, Frank immigrated in 1907 and Helen immigrated in 1912.An interesting thing about the 1930 - Frank and Helen are both listed as born in Austria.All of the children have their father born in Austria and their mother born in Hungary.I am wondering if Frank was previously married and Helen is not the mother of all of the children.
This is Helen's petition for naturalization. https://familysearch.org/pal:/MM9.3.1/TH-1-18235-48868-23?cc=1909003
It says she entered the country under the name Ilona HALASZ aboard the S.S. Carpathia on 16-April-1911.Her birth date was 26-Dec-1892 in Vizsay, Hungary.She married Frank BARATH on 2-Aug-1926.It lists 6 children and 5 of them have birth dates that occurred before they were married.
