How can I complete repentance when someone won’t respond to my request for forgiveness?

Details:Some years ago HaShem showed me the error of my ways, I was a Christian. I approached each of my family members to request their forgiveness for having lead them astray. Three of my seven children forgave me, four and my wife turned their backs to me and refused to listen. I tried to ask for their forgiveness more than 3 times over the years. My wife finally gave me ear and forgave me, though she did not agree with me. Four children still refuse to hear me and will not respond. I am a Noahide now. I am deeply troubled over this issue.
