Hi I-Bob,
The New Testament, specifically the Book of Acts, is the only accurate history of the Church and the Apostles that I know of.
There are snippets of information here and there, but no truly reliable historical sources. When we find early church histories in the 2nd century A.D., we find customs different from the practices of the Apostles.
In the New Testament, we see where all of the churches in the province of Asia Minor (modern day Turkey) had rejected Paul, and that area had been the center of Paul's work. We see where Peter was having problems with church members rejecting his teachings and authority. We also have a Scripture showing that the Apostle John was rejected by a church leader.
The Book of Acts was written by Luke, who was a close associate of Paul, and especially the later chapters of that Book focus on the Apostle Paul up to the time of his imprisonment at Rome.
Paul in Galatians 1:17 through Galatians 2:1 covers briefly his early years.
Apparently Paul and Peter were executed by the Emperor Nero in Rome sometime in the early to mid 60's A.D. John lived on until the end of the 1st century A.D., a very old man, seeing to the completion and publishing of the New Testament. At the end, he is associated with the City of Ephesus in Asia Minor.
Like I said, not much true history to go on outside the New Testament.
Take care,
John
