I am researching these families for a friend:
Stephen Vittek (b. 1885 d. ?) md. *Gisela or Gizella ? Suina? (marriage certif) or Gulyas b. 1892 (shown as Hazel in 1920 census)
ch: Marie b. 1916 and Stephen b. 1918 (both deceased)
It appears that Stephen and his wife separated (or she died?) as the children were in the St. Joseph's Orphanage in 1930.
We are wondering what became of the mother. The father is in 1940 in Erie, "married" but no wife with him. Was he still md. to Gisela? or to another woman?

Also interested in:
Joseph Duska (b. 1879) and Mary Vitek (b. 1882)
They also lived in Erie; from Mary's immig. record it appears she may have been from the same town as Stephen Vittek!

Hoping the Duska family can shed some light on the Stephen Vittek family.
