What text type did the early church fathers use?

In 2007, John Oakes answers the question, What text type or types do the most early church fathers use? He answers that the “Alexandrian” text type is closer to the original writings of the New Testament. Then, to add insult to injury, he adds, “If a supporter of the KJV says that the church fathers from the second century used the Byzantine text, you can be assured that this person is either misinformed or is extremely biased. You would do well to ignore such a statement.”

Oakes does not provide space for questions or comment. This extremely biased misinformed person, rather than ignoring his statement, would have liked to asked a question or two.

From what text type were Irenaeus of Lyons (2nd century) and Cyprian (3rd century) quoting when they referred to what we know as Acts 8:37? The Alexandrian or Byzantine? From what text type did Irenaeus (2nd century) quote when he referred to what we know as Mark 16:19? The Alexandrian or Byzantine?
