Thank you for your kind reply:
I orderd Alice Thompson death certificate of

But she was still born on 1 Aug.

Name: Alyce Isabelle Thompson
Death Date: 4 May 1986
County of Death: Polk
State of Death: Florida
Age at Death: 82

But she does not appear to be my Alice.

I will ordred today for:

Today and also for:
