Hi M.,
Your situation is heartbreaking to me and I am sorry it is causing so much angst and grief.
Is there any way you can go to your son & daughter-in-law's home, preferably not alone, to see for yourself what is going on? What about your other 2 sons. DO they have any idea what to make of this situation?
I do hope you get some answers soon and are able to reconnect with them, especially your grandchildren.
May God bless you M..
