Kreis Arnsberg/Forscherkontakte

I am searching for my ancestors in Kreis Arnsberg. My great grandfather, Johann Faerber migrated to the USA in 1854. I found his birth/christening in Sankt Johan Baptist Roemisch Katholische, Allagen Westfalen, Preussen Apri. 1829. His parents are Franciscus Christophorus Ferber Faerber Christening June 1803 Sankt Johan Baptist Roemisch Katholische, Allagen, Westfalen, Preussen and Elisabetha Blugge. They were married 29 Nov. 1828, in the above given church. I want to know: 1. If they had another children? 2. What was his occupation? 3. When did they die? 4. Where are they buried?

Franciscus Christophorus Ferber/Faerber parents are given as: Thomae Thomas Ferber Faerber and his wife, Elisabethae Droege Marriage 06 Nov. 1787 listed at the same church as above.

I want to know: 1. His correct name 2. Where is he from? 3. Who are his parents and where are they from?

I am aware that some of this information can be found in the Kirchenbuch 1691-1874 Katholische Kirche Allagen (Kr. Arnsberg) 357846

How do I get this information from this book?
