moonfire on Family Tree Circles

Josephine was born 1809 in France. Her father was Henry Dupont.
She married Francis X. Wachtler abt 1835. In 1836 the family immigrated to the USA. Daughter Amelia was born in 1838 in Pekin, Ill., daughter Josepine Eva was born in 1841 in Vicksburg, Mississippi.
In 1843 son Augustus was born in Illinois. In 1849 son John Henry was born in Quincy, Ill. The family moved around a lot, finally settling on a farm in Wingville, WI. (now Montfort).
In 1862 Josephine died and was buried in Ebenezer Cemetery, Preston, WI.

I'm looking for Josephine's maternal ancestors (her mother and grandmother). Any help will be greatly appreciated.
Thanks so much.
