Anything really...
How did they meet?
When did she come to the US?
Does she know any history of the Fornaro aka Fornara family that will complete or augment what I know?
Does she have any old family photos of her father-in-law and family further back she might consider sharing?

She may even hold clues, without realizing it, as to whether or not more of her late husband's family beyond his grandfather Benedetto & uncle Giuseppe came to America; this is something I've been trying to find out about for years.

I know this is a dead branch that will end with her since she and Bernard had no children but still if she is so inclined to reveal her history, I'd like to fill-in some of her ancestry as well since she is a member of the family.

I'd love to learn what her experiences in Japan were post war & during the war. What were some of the traditions? What was it like growing up in Japane & living through the war? What was the average Japanese citizen's view on the war?

I'd like to share with her what I know of the Fornaro/Fornara family if she desires to know about her late husband's heritage.

As I said, I know next to nothing about her. In this day & age of so much information gathering & transparency in everyone's lives, she is one of the rare few to have managed to remain below the radar.
