The new bf and her family are denying us visitation to our beloved grandchildren

Barbara Cowlier, from Lake Orion, Brandi' s mother and Kathleen Taylor, her grandma from Clarkston have denied us access and visitation and contact with our grandchildren, despite the fact that they have been absent for the last 2 years completely from their lives except birthdays. When Brandi was homeless I took her in and those children have lived with me and my mother for the last 2 years straight, they just moved out lately and this is so wrong to put another trauma to our poor grandchildren.
