where could I find an immigration list of the 1840s into Jefferson county Mo.? They left Bordeaux France in 1840 , and then They are in the 1840 census of the Big River Township of Jefferson Co. I thought that They were in Canada , for several years , Their names are John Roque and Eugenia (Bernadette) Roque with one daughter CORA . CORA was born in 1833 and they left France when She was 7 years old , so They must have came straight here , unless They went to Canada , and then just walked across the border Thank You ; Karl Roussin
