Descendents of George Albert (Pieszak) Pioszak, Manistee, MI

I am researching descendents of George Albert (Pieszak) Pioszak and Josephine Ozdych (Pieszak) Pioszak of Manistee Michigan. The family immigrated to Manistee in 1878. There were a total of 10 living children. Children were Agnes/married to Ladis Cierpka; Theophelia/married to Joseph Swiderski; Francis (Frank)/unable to locate;Mary/married Edmond Jankowski,Milwaukee,WI; William/married to Joanna Pasinski, Ludington, MI; Stephen/unable to locate; Theresa/married to Edward Swidorski; Blanch/married to Chester Waier; Salma/died as child; Anna/married Frank Socar, Milwaukee, Wisc.

I am the Grandaughter to William and Joanna Pioszak. My Grandfather died when my father was 16 years old and most information was lost regarding my grandfather's family. I have a great desire to find out what happened to that part of my family.
