Eddie, you are appreciated. Cared for. Valued. Julie is correct though in that IF THE FAMILY members any of them are approachable it would be an avenue of information. If not all the other ways suggested are also viable.
My mother had a sister she refused to have anything to do with; of my two sisters neither one ever had a good thing to say about the other and they still hate each other after 80 years.
A family can fracture, splinter, scatter, drop out of sight, etc.
