In Georgia does a sibling have vistation rights?

No they do not have any rights to there grandchildren whether it be visitation or anything unless they have taken care of the child for at least 6 months in a row then they can go through legal procedures to get visitation.

The laws regarding visitation rights for grandparents vary from state to state and are often determined on a case-by-case basis.

Briefly, all states require that the grandparents have the burden of proving the visits are in the best interest of the child. Be advised that when the grandparents are trying to wrest control of grandchildren of their deceased child from the surviving parent- that type of situation may not be considered to be in the best interest of the child.

Some states are more permissive: Connecticut, Hawaii, Idaho, Kentucky, Maryland and NY. Other state are more strict such as Florida, Minnesota and Pennsylvania where the child must have lived with them or they must have had a parent-child relationship with the grand-child. Some state requirements are extremely narrow where the grandparent must prove they took the child to normal activities such as doctors appointments or school and they cared for the child over extended periods.

You need to consult with an attorney in your state who can review your situation and explain your options.
