Hi
My friend's husband's grandparents were Michael and Rose Gibas from Chicago. I know Michael's son he still lives in the area. I think you are looking for the same people Rose spelled her name Pyclak. and their oldest was born in 1913 which would be right since you state that they married in 1912.

Please respond to my email address: m.hiller@inil.com if you think these are the same people?
