That´s nice, thank you for your message. Barba FORMAN was born either in 1838 or 1839 (I have to check in again). According to the birht record she was named Marie Elisbeth, but for some reason she was called Barbara. I assume that this her baptize name. She crossed the ocean onboard the ship SCRANTON. I have the passenger list if you want to have a copy. She died in 1910, I have a copy of her tombstone, made in June this year, when I visited the cemetary in Dubuque.
Her uncle Michel FORMAN, born in 1811 was the brother of her father and emigrated in 1843 onboard the ship Cahacoba. You may see it on the site of the Immigrants Ships Transcribers Guild. I have also a document where he donated his bed etc to his brother, John Peter, probably the father of your Barbara.
That´s all for the beginning, I propose to exchange more data per e-amail.
