Miok, check at the county courthouse probate court/surrogate court to find out if your grandmother had an estate that was probated--if she did, then look at the file or order copy of the page that shows the will and the name and address of the executor. If executor is still living, they may be able to take care of this for you and distribute the monies to all legal heirs. If there was no estate, then you will need to consider whether it would be worth it to hire a probate attorney to get an estate opened up for this or whether you would want to serve as administrator yourself.
