The Geideck Family Home Page

I am searching for Geideck, McCormack, Marker, Fairchild, Hay family names. More will be added later. I was born in Des Moines, IA. The Geideck name came to the U.S. about 1850 to 1875, the Fairchild name was mentioned to be from the Penn. area and the McCormack name was mentioned in conjunction with Danel Boone. The Hay name came from Aberdeen Scotland. I know I am very vague right now, but I am just starting and have not gathered much information yet. I would appreciate any help and will share any information I have and or gather.
