Genealogy / Poris, any info on this surname? [11]

Hello to All who read this!
I am searching for information on my family and I get to the brickwall called born in Poland/Germany, on records I have reviewed. I know this: My great grandfather was born in 1845 +/- and emigrated between 1890-1892 with his wife and 3 children to Detroit MI.

Can't find his wifes name. His name Was Pawel (Paul) Scriykowcki, his oldest son was Frank, second eldest was Joseph youngest was my Grandmother Anna after in Detroit they had a third son Paul. I believe my great grandfathers trade was a printer. I also believe from conversations with my grandmother that I remember, that she said they were Kashubs and had come from Danzig. I have been unable to move beyond this and have tried for several years. I also can find no records of their imigration or any passenger list with names. I have searched both Polish and Kashubian data Bases with no names even close. Do any of you kind folks have any ideas or things I might try or better yet any information.

Thank You in Advance for any light you can bring
Lee USN Ret.
