StackLayout in RelativeLayout, not showing StackLayouts Childrens..

Hey there,
I'm currently trying to show Images of People with their Name below the image and their skill.
All this should be displayed in a grid like layout. Attached an image how it should look like.

I'm currently trying to do this with the following code, using a relativeLayout and putting a stackLayout inside, which stacks the image and the label and the skill.

`

    var picture = new ImageCircle () {
    Source = ImageSource.FromFile("Girl.jpg"),
    };

    var name = new Label {

        Text = "Vangelis Threecups",
        //TextColor = Color.FromRgb(255,128,0),
        XAlign = TextAlignment.Center,
        YAlign = TextAlignment.Center

    };

    var skills = new Label {

        Text = "#Designer",
        TextColor = Color.FromRgb(255,128,0),
        XAlign = TextAlignment.Center,
        YAlign = TextAlignment.Center

    };

    var box1 = new StackLayout {

        Orientation = StackOrientation.Vertical,
        HorizontalOptions = LayoutOptions.CenterAndExpand,
        VerticalOptions = LayoutOptions.CenterAndExpand,
        Children = {picture, name, skills},

    };

    double padding = 30;
    layout.Children.Add( box1, () => new Rectangle(((layout.Width + padding) % 60) / 2, padding, 90, 90));

    var last = box1;
    for (int i = 0; i < 200; i++)
    {
        var relativeTo = last; // local copy

        var box = new StackLayout {

            Orientation = StackOrientation.Vertical,
            HorizontalOptions = LayoutOptions.CenterAndExpand,
            VerticalOptions = LayoutOptions.CenterAndExpand,
            Children = {picture, name, skills},

        };


        Func<View, bool> pastBounds = view => relativeTo.Bounds.Right + padding + view.Width > layout.Width;
        layout.Children.Add(box, () => new Rectangle(pastBounds(relativeTo) ? box1.X : relativeTo.Bounds.Right + padding,
            pastBounds(relativeTo) ? relativeTo.Bounds.Bottom + padding : relativeTo.Y,
            relativeTo.Width,
            relativeTo.Height));

        last = box;
    }`
