looking for info on George and Maria Blace.
children. George jr., Michael, Catherine, Sarah, Mary Ann, Rebekkah, Samuel B.
George b abt 1823 France
died. about 1866 Iowa, USA
also lived in Ontario, Canada
Maria. b. about 1835 New York State, their son George was born in Ontario...July 1850
I assume you are looking for info about George & Maria going back from Iowa and that you have the information on the children going foward?

Food for thought
A couple things have caught my eye.
In the 1860 census the closeness in age between Mary and John is only 13 years? Is she the mother?
Also sons John & George are listed as being born in Canada West. Son Michael in Iowa?.
But in the 1870 census and those after, son Michael is listed being born in Canada also.
I think Mary(Marie) may not have been the mother of all those children and George was married previously?
This 1851 Canada West census caught my eye. It has a George of about the right age with sons named John, George & Michael about the same ages listed for the children in following censuses. He is married to an Eve and his POB is listed as the Netherlands.
