Frederic Chouinard married Celeste Lefebvre

Frederic(k) Chouinard/Swenor married Celeste Lefebvre probably about 1841.
They had a daughter, Marie-Helene in 1842 in St. Valentin, St. Jean County, Quebec.
By 1850 the family is living in Chazy, New York.
By 1860, the family consists of 8 children:Helen/Ellen, Frederic(k), Delia, Phoebe, Sarah, Henry, Abraham & Edward and are still living in Chazy, New York.I believe they also had a son, John about 1863.
Most can be found in later records in Vermont.
Would love to find out who Frederic(k)'s parents are and where Frederic(k) and Celeste married.
Thank you in advance!
Sincerely,
Charlene
