I believe that Charles C. Sobek b. about 1878 who married Mary Michalek is the son of August Sobek b. about 1852, and that Charles/Karel Sobek and his wife Maria Belik had 8 children, none of which was named Charles.
The names of the 8 children from 1st generation in Muscoda were used over and over again in later generations, so it becomes quite confusing just which Charles is which. Rose gave me the names of the first generation 8 children of Charles/Karel Sobek and Maria Belik.
The father of Charles/Karel Sobek is Joseph Sobek who married Anna Mensik. Recently a relative of mine who lives in Prague was able to photograph the home of Charles/Karel Sobek and also the home of John Belik and Mary Vesely Bilek. (Charles/Karel's in-laws). They photographed the only Catholic Church in Cervena Recice that is very very old and that the Sobek Family no doubt were members. I know my grandmother was Catholic, who was one of the 8 first generation children.
Hope this helps you a little.
