People with the Sash Surname in the US appear to be decended from a number of independent immigrants primarily directly from Germany.
My surname is Sash and I know my Sash Ancestors in Bureau and Pike Counties in Illinois back to my Great Grandfather Henry Sash who appears to have been orphaned during the Civil War. He lived with a Ham family until he was old enough to work as a farm laborer.
I believe that he is the son of Philip and Dinah Sash who emigrated to Springfield, Illinois from Baden, Germany in the early 1850's. I think Philip Sash was killed in the Civil War in 1864 and is buried in the National Cemetery in Knoxville. I would like to know what happend to Dinah Sash and her child Edward who appear to have disappeared between the 1860 census and 1870 census. I have not be able to find a record of Dinal remarrying,
I will probably have to go to Springfield to attempt to find the death records.
