John Mark
Mark 14:69ESV·traditional attribution
And the servant girl saw him and began again to say to the bystanders, “This man is one of them.”
Matthew Henry Presbyterian @wholebiblehenry
We have here the story of Peter's denying Christ. 1. It began in keeping at a distance from him. Peter had followed afar off (Mar 14:54), and now was beneath in the palace, at the lower end of the hall.

Geneva Bible Notes Reformed @genevanotes
And a maid saw him again, and began to say to them that stood by, This is [one] of them. (q) If we carefully compare the evangelists together we will perceive that Peter was known by many through the maiden's report: furthermore, when the second denial is spoken of in Luke, there is a man servant mentioned and not a maid.
