No, my dad was awful in life, he needs to stay dead and away from me, far away, as do my grandparents.
As for my 3 infant sons that died, I think about them all the time. But, no, I don’t “speak” to them.
However, when I visited my great grandmother’s grave, (my father’s grandmother) a woman I don’t remember ever meeting, I was given a great sense of peace, a feeling that I was truly home, and loved.
It was, as if, she had been waiting for me. The graveyard was in a small “old” town in the middle of nowhere close to the dirt farm my father was partially raised on. I have read, since that incident, that other people, researching their family and visiting the old graves, have had this experience as well.
