RosieRoberts on Family Tree Circles

I am looking for a woman named Goergene Beneires. She was born in Omaha, Nebraska abt. 1929. At one point she was married to Clarence Casey of Omaha, and they had two children together. That was around 1946.
In 1951 my dad was born in Abilene, Kansas to Georgene, and Eldon Roberts. Only a few years later she was gone, and my dad was raised by his grandmother.
Through my research, I found that Goergene's father came to The US in 1914 from Greece. He lived in Omaha, Nebraska until he passed in 1971.
Anyone who may have known her, or her father I would really appreciate any information. I don't know if my grandmother is still living, or not. But I would like to find any living family members.
