I'm not sure if my grandmother is related, but she arrived in 1921 on the Berengaria when she was 8 years old. The manifest states her name as Mari Kosc, which was changed to Kost. I know she had several brothers and sisters, living in the Eastern PA area and Connecticut. My grandfather was a coal miner also, but his last name was Wasicko. I too am looking for any info.
