Im working on the history of my family and when I got to my grandfather's side I got lost. His name is Rudolph Olbera which I learned is the American way of spelling Olvera. He was born in Chicago, IL but his parents were from Mexico. They came to the states legally and Im not sure where they originated from. If anyone has an information please email me at jc_bluejay07@hotmail.com. Thanks for any help you can give me.
