What happened to the father of Noah

Methuselah became the oldest man that ever lived; he lived in the blessing of his father Enoch and became 969 years. Methuselah had Lamech the father of Noah who was to continue the humankind on earth after the flood. Lamech the father of Noah did not become 900 years or more, no he died at the age of 777, God saved him from the flood, Lamech died just a few years before the flood came.

Lamech is prophesying of Jesus Christ

In verse 29, Lamech said that his son Noah would bring them rest and comfort from all the hard work with the soil that the LORD cursed. Lamech is calling God by His name YHWH; this was the common name on God from the beginning. Lamech is talking about rest and comfort, and this is a prophecy of the coming of Christ Jesus.

How did God protect Noah and his family?

Noah also walked with God as Enoch did and preached to family, friends, and all around him. God denied the wife of Noah, children until Noah was 500 years then they had Shem Ham and Japheth. The sin had a devastating effect on people and the society, but God protected the children of Noah by him having children late in life and soon the building of a huge box to float on water occupied all of them.
