Hi Kevin!
I am researching a John Kaminski (wife Mary Adamczyk-my great grandfather's sister) late 1800s to present. I don't have all my Kaminski info. handy at the moment but let me check my info. and get back with you. What exactly do you need? I live near Grand Rapids so maybe I can help you out even if my info. doesn't produce anything for you. Let me know! swiatekc@river.it.gvsu.edu
