First, I'm sorry for your loss.
AFAIK, there's no registration requirement in Georgia. But the safest course would be to have the pistols sent to an FFL in George for transfer, on a 4473, to the OP.
Now there's the general rule that:
"It shall be unlawful...((3) for any person, other than a licensed importer, licensed manufacturer, licensed dealer, or licensed collector to ... receive in the State where he resides ...any firearm ...otherwise obtained by such person outside that State, except that this paragraph (A) shall not preclude any person who
lawfully acquires a firearm by bequest or intestate succession in a State other than his State of residence from transporting the firearm into or receiving it in that State, if it is lawful for such person to purchase or possess such firearm in that State,...(18 USC 922(a)(3), emphasis added)
But the question is whether the two pistols at issue here were lawfully acquire by bequest or intestate succession, and I'm not absolute sure that they were.
"Bequest" means, "...the gift of personal property
under the terms of a will...." (

Was there a will here? A "will" is, ".... a
written document which leaves the estate of the person who signed the will to named persons..." (
http://dictionary.law.com/Default.aspx?selected=2248, emphasis added) And a will generally must be filed with a court for probate so that distribution of the assets is done under court supervision. But there doesn't appear to be any written will here, nor does there appear to be any proceedings in probate.
Were the pistols transferred by intestate succession? Again it doesn't appear that they were.
"Intestate succession" is:
"...the distribution when a person dies without leaving a valid will and the spouse and heirs will take (receive the possessions)
by the laws of descent and distribution and marital rights in the estate which may apply to a surviving spouse...."(

In various jurisdictions, various laws of decent define how property of someone who dies without a will would be distributed among surviving family members. Usually such distribution requires that someone be appointed by the court to be the administrator of the estate, and the distribution is then carried out under court supervision.
In this case, it's most likely that the surviving spouse acquires the pistols by intestate succession. She is then making a gift of them to the OP.
Thus it's possible that the exception of 18 USC 922(a)(3) doesn't apply. In that case the safest course would be to have a transfer done by an FFL in Georgia.
While the foregoing analysis may appear hyper-technical, let's remember that AFT has no sense of humor about these matters and is, indeed, very much inclined to be hyper-technical.
