Andrew, I am Mildred (Rackerby), Archie and Estelle Rackerby's daughter. I talked to your dad several times and he shared some information with me. He sent a picture of our great grandfather John J. Rackerby, only it was a xeroxed copy and I can't make out the faces. It came from Winston so I don't know if he had a photo copy of it or not. I have no pictures of Dr. John so if you come across any let me know. We did (my brothers and sister) have a marker installed in Omaha Neb. where our gggrandfather Joseph is buried. If you would like a copy of that info let me know. Thanks.
