Gehrke research

Is anyone researching the GEHRKE name. I am interested in finding someone with information on Gehrkes from the village Sellnowo in Graudenz county, Westprussia.

From Castle Garden records I know the following:

Name, Pauline Gehrke
Age, 19 (born 2 Oct 1871)
Arrived, 15 May 1890
Origin, Germany
Port, Antwerp
Last Residence, Sellnowo

Father, Wilhelm Johann GEHRKE, born 21 Feb 1835, mother unknown.

Thank you. Donna
