Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

I am researching my genealogy. My Great Grandfather Anthony Spewock was born in Ropica Ruska, Galicia in 1884. He was Ruthenian. His Last Name was spelt several different ways on documents here in the States. Spiwak, Spiewak, Spivak and Spewock. They were Greek Catholic and the Church in Ropica Ruska was St. Michael the Archangel. His parents were Joseph Spivak and Anna Bonitsky. I cannot find records at Ellis Island and am wondering if the name is spelled differently in Polish.

Also Searching for records of My Great Grandmother Paulina Cherrup. Born in Perunka in 1891. Her fathers name was George Cherrup and her mothers was Helen Slusarczyk. Cherrup may also have been changed. Perhaps shortened?

I would appreciate anyone information anyone might have on these Surnames.

Also, what are the meanings of those surnames? And does anyone know how to contact a church in Poland. I know absolutely no polish and am confused about the mailing addresses and phone numbers. I found and address but it seems incomplete. What does a Polish address look like?
