My ancestor was Agatha/Agate Besanson. We have her birth as 12 July 1806 in France and her death was 6 Sept. 1889 in MN. She married Augustus/Augustin Brossard and they were the parents of 10 children born from NY to WI from 1831 to 1853.
I suspect that she is the child of Anthony & Frances Besanson/Bezonson who came to the US in 1827 even though the ages don't match exactly.
I would love to find a concrete connection to Agatha's family.
