"ok, we can solve this by declaring one bool variable (flag) and checking true/false" , my architect says "no flags please!!". Any thoughts why flags not recommended?

As an alternative you can define your own enum with two (or more) more meaningful values.

DataGridViewComboBoxCell cell = new DataGridViewComboBoxCell();
cell.Items.Add("0");
cell.Items.Add("1");
cell.Items.Add("2");
cell.Items.Add("3");
dataGridView1.Rows.Add("test", cell);

private void button1_Click(object sender, EventArgs e)
{
    DataGridViewComboBoxCell cell = new DataGridViewComboBoxCell();
    cell.Items.Add("0");
    cell.Items.Add("1");
    cell.Items.Add("2");
    cell.Items.Add("3");

    dataGridView1.Rows.Add("test", cell);
}

List<int> peopleUsed = new List<int>();
Random r = new Random();
int person1Index, person2Index;
person1Index = person2Index = 0;
while(peopleUsed.Count < people.Length) // people is the array of people
{
    if(!peopleUsed.Contains(person1Index)) // make sure person1Index hasn't been used
    {
        // find a person2Index that hasn't been used
        do
        {
            person2Index = r.Next(0, people.Length);
        }
        while(peopleUsed.Contains(person2Index) && !peopleAreInSameFamily(person1Index, person2Index)); // also make sure they aren't in the same family!
        // DO SOMETHING WITH THE 2 PEOPLE
        peopleUsed.AddRange(new int[] { person1Index, person2Index }); // add the two person indexes to our used list
    }
    person1Index++;
}
