They had2 daughters. Elaine and Carole. I'm the daughter of Elaine and have hit a wall

My grandfather was Joesph Detloff he married Anne Kaldis. they had 2 girls. I am looking to find out information about his side of the family. They lived on the south side of Chicago. If any one can help with the Detloff Family or the Kaldis Family please contact me and maybe we can compare our information and see what we have. I have some information on Detloff but hardly any on the Kaldis side.
