Julius Auberzinski Auberzinsky Aubersinski

Good day all, I am research family of Julius Auberzinski. The spelling of the last name is different on many of the censuses. The family name is Auberzinski. But has been spelled Auberzinsky and Aubersinski. I am looking for any information I can get from family members or anyone willing to help me with research in the Pennsylvania area. The family came over from Germany and were coal miners in the Cambria area. Also in Blacklist(?) area. I have had contact with one family member that states they have the naturalization paperwork and the name was spelled differently. I asked if he was able to give me the information on said paperwork and he has not responded back to me and that was over 3 years ago. Any information that I may be able to get will be greatly appreciated. Thank you in advance.
