Hi Pamela,
You need to find out who took care of Alice's estate.
Who organised and paid for the funeral.
At some point a solicitor would have been involved.
We cannot do that for you and chances are only your husband can.
Contact the cemetery and funeral directors then follow on, trying to find any legal documents (will/probate) to see who is named.
Again, someone had to finalise her estate and chances are they took possession of the medals.
