I can see them on the US census - one daughter Clara but also three sons, are you aware of this? (Won't name the sons - I can
familysearch.org shows them together in 1940 - where the eldest child was a son born about 1921 Ohio.
There is also a death for Vincent Kasiorkiewicz b. 05 Jul 1894 d. 25 Aug 1950, parents Casimir and Magdalene.
A marriage in Ohio, 1919, for Vincent Kasiorkewiecz and Helen Gajewicz
And both WWI and WWII cards for Vincent:
Vincent Kasiorkiewizz (WWII) - gives him as 05 Jul 1893, place of birth Warsaw, Poland
Wincenty Kasiorkiewicz (WWI) - gives him as 05 Jul 1893, place of birth Swierczynik, , Russia
Other censuses are hard to find because of the variant spellings. Think "Vincent Kasurkiewcz" in 1920 - and John Geyewicz with him is probably the father in law (although on the index his relationship is not given), and Vicent Kasnubiekiewicz in 1930 - where it states that he emigrated in 1913 and Helen in 1908.
Interestingly, there are also two sons in 1920 and 1930 who were born before the 1919 marriage - it's not clear if they were from either Vincent or Helen in a previous relationship, or if they were together before 1919 but weren't able to marry until after the war for some reason.
