You may want to try the following prayer. It is intended for family. I got it from a website I found via this website:
Healing the Family Tree 3
Heavenly Father, I come before you as your child, in great need of your help; I have physical health needs, emotional needs, spiritual needs and interpersonal needs. Many of my problems have been caused by my own failures, neglect and sinfulness, for which I humbly beg your forgiveness, Lord. But I also ask you to forgive the sins of my ancestors whose failures have left their effects on me in the form of unwanted tendencies, behavior patterns, and defects in body, mind and spirit. Heal me, Lord, of all these disorders.
With your help I sincerely forgive everyone, living or dead members of my family tree, who have directly offended me or my loved ones in any way, or those whose sins have resulted in our present sufferings and disorders. In the name of your divine Son Jesus, and in the power of his Holy Spirit, I ask you Father, to deliver me and my entire family tree from the influence of the evil one.
Free all living and dead members of my family tree, including those in adoptive relationships, and those in extended family relationships, from every contaminating form of bondage. By your loving concern for us, heavenly Father, and by the shed blood of your precious Son Jesus, I beg you to extend your blessing to me and all my living and deceased relatives. Heal every negative effect transmitted through all past generations, and prevent such negative effects in future generations of my family tree.
I symbolically place the cross of Jesus over the head of each person in my family tree, and between each generation; I ask you to let the cleansing blood of Jesus purify the bloodlines in my family lineage. Send protective angels to encamp around us and administer your divine healing power to all of us, even in areas of genetic disability. Give special power to our family members’ guardian angels to heal, protect, guide and encourage each of us in all our needs. Let your healing power be released at this very moment, and let it continue as long as your sovereignty permits.
In our family tree, Lord, replace all bondage with a holy bonding of family love. And let there be an ever-deeper bonding with you, Lord, by the Holy Spirit, to your Son Jesus. Let the family of the Holy Trinity pervade our family with its tender, warm, loving presence, so that our family may recognize and manifest that love in all our relationships. All of our unknown needs we include with this petition that we pray in Jesus’ precious name. Amen.
The website I got the above prayer from is called The Catholic Warrior, and I found the above prayer under “Warfare Prayer”. This is the website: catholicwarriors.com/default.htm
The Bible mentions generational curses. Through no fault of people, they may inherit a generational curse, and thus start acting in a manner contrary to the manner in which they were brought up, etc.
Also, you may want to bring in a priest into this situation, and talk to him, and have you, your husband, and your home blessed, and if at all possible have your son and his girlfriend blessed.
God bless you all, and I will continue to pray for all of you.
Heavenly Father, in faith, I thank You for helping and protecting Vicki and her husband. In faith, I thank You for taking care of Viki’s son and girlfriend, and guiding them to Your road. Amen.
