A Christian tradition says that Matthew, Luke, Mark and John were the authors of the gospels that bear their names. Certainly the gospels were written by real, historical people, but they were originally anonymous works. It was only later in the second century that the Church Fathers attributed each of the New Testament gospels to the apostle they thought most likely to have written the book. The existence of the gospels is therefore not proof that people known as Matthew, Luke, Mark and John were historical people.
As to whether the apostles of those names were historical people, there is no extra-biblical evidence. It is possible to believe in their likely existence on the basis of biblical testimony, but it is not possible to prove that they really were historical people.
There is no record or historical evidence to confirm whether Saint Matthew had any children. The Bible does not mention any descendants of Saint Matthew.

Matthew, Mark, Luke, John, and Acts. Revelation is a prophetic book and all the others are letters or epistles.
Matthew John Morley is 6'.
Of course, if Matthew and John were two of the twelve apostles, they would have known Jesus. However, scholars now realise that Matthew and John were not really the authors of the gospels that now bear their names, with those attributions only being made by the Church Fathers later in the second century, based on the limited evidence by then available. We do not know who wrote the Gospels of Matthew and John, but it is clear that they could not have known Jesus.
