Got letter back today from my source on Teresa Kosheski Groth which is her great grandson. He said Teresa did have a brother named Rudolph. He is very busy with his farm now but says he has lots of information on Ferdinand Groth family. His mother was the record keeper, but she has died. But he has a lot of letter from Okla and Arkansas inquiring aboutthe Kosheski family. Its probably going to be awhile before I get anymore information from him.
