Hi, Jodi. Let me see if I have this right. Your gg gpts are Charles and Staze (unknown) Sramek. They are listed as bakers in the 1917 Cedar Rapids directory, and the 1937 directory shows the bakery at the same address, 1100 S. 7th.
To answer your question about the census, some states had censuses on the half-decade years, e.g. 1885, 1895, etc. I checked Ancestry; they only list the Iowa 1885 census. That does not mean there weren't other ones. You can sometimes check out a microfilm with an inter-library loan. Hopefully you can find a librarian who will help with this. If you live in a large enough city, a local genealogical society would love to help. Sometimes the special censuses listed very interesting facts. The 1885 census in Nebraska lists how many horses, cows, and chickens my great uncle owned.
I checked the social security death index, and there are two Charles Srameks listed for Wisconsin. One was born 1894, died 1966. The other was born in 1924, died 1998. It costs quite a bit, ($27. I think) but you can order a photocopy of the original application. For my relatives, it listed the village in Europe where they were born. Of course, if the 1894 Sramek was born in the US, this will not help you much. But if he WAS born in Europe, it would have his village.
I don't know how the churches are in Iowa; here in Nebraska one diocese does not permit anyone looking at the old directories. But if your ancestors were Catholic, you could check with the Czech parishes in Cedar Rapids, and see if there is a baptismal record for Charles II. Once in a while the priest listed the village in Europe of the parents.
I am interested in your Srameks, because we don't know where our Srameks were from 1877 to 1882. Yet they ordered a cemetery monument from Spillville, IA. We have often wondered if they spent part of that time in Iowa. However, since Charles was not one of the names used, I consider it unlikely that your Srameks are closely related to my Srameks.
To summarize: if the Charles Sramek who died in Wisconsin is your relative, consider buying the Social Security application copy. Check church records. If anyone in the family has the original documents brought over from Europe, examine them for the name of a parish or village.
I couldn't tell from your message: are you researching back into Europe, or forward into the US?
