Where can you find a biography of the biblical Mark of the New Testament?

Since so little is known about Mark, otherwise known as John Mark, it is unlikely a specific one exists. The details of Mark can be found in any good Bible Dictionary.

The Bible references to him are as follows: Acts 12:12, 25; Acts 15:37,39 and 2 Timothy 4:11.

Some also believe the reference to the young man who fled at the time of Jesus' arrest, only found in the Gospel of Mark, is a reference to Mark himself. Naturally he would not wish to admit to being the person, but also, there would seem to be no significance to this event, or any importance, except to a personal participant. This is in Mark 14:51-52.
