I am looking for information on my maternal grandfather. The information I have found is that he was born in Mielec Poland on Jan. 30, 1887. He immigrated to the US in 1903. He had a sister Kathryn born 1896. He brought her to the US in 1910. He married a woman named Bertha Witkowski in Pennsylvania approx 1909. She died shortly after my mom was born in 1925. He went by either Herchel, Hershel or Heller in the US.
I'd appreciate any information you can provide.
