Surnames Polanka, Hozman, Pinkas

Looking for ancestral information on Matthew (Matej) John Polanka from Drazovice, Bohemia, b. 19 Dec 1870. Father is Matthew, mother is Magdalena Hozman (Hozmanu). Immigrated to Baltimore, Maryland in 1888. Magdalena’s first husband died and she remarried. She had children from first and second husbands. Don’t know if Matthew Polanka was first or second husband. There is a genealogy history (Rodomen) on the Hozmanu family, which an aunt was trying to get translated. She passed and no one knows what happened to the book. Could have been sent to a relative in Bohemia.
Matthew John Polanka married Antonia Maria Stach in Baltimore, MD, in 1892. Looking for information on Matthew John’s siblings/half-siblings. The name Pinkas shows up as relative from Drazovice also.
