I recently accessed this website and found your message.Although several years have passed since you sent your inquiry about Adolph Karluk, I may have some information that might aid your hunt.
I believe my father, Adolph Karluk, was your great grandfather's nephew.My dad had relatives that lived in Washington, PA.My aunt visited them frequently and one of those people was my father's uncle (your great grandfather?).
The information from my cousin's son from Monroeville is partially incorrect.
If you still are visiting this website, please leave a message and I'll reply with any information that I have.
