Cheskel Shraga Sander - Date of Death is incorrect

Hi,

I'm a Sander grandchild, and have been looking through my family tree. I came across that the information entered regarding my great, great grandfather, Cheskel Shraga Sander father of, Shloima Zalmen Sander is incorrect. He perished in Aushwitz, and the information listed on Geni shows that he passed away in 1965. I would appreciate if someone can update the file with the correct information.

Thank you.
