No not yet
If it
is my Jacobs family, my GGG grandma has already been found listed as Eleanor and Elmira - neither of which could possibly be the name on this census - so what's another alias! LOL
UPDATE:
I have found this family on 1850 USA census & her name is Rosamund! Among the children living with them is a Jane. This is possibly my Emma Jane, as she is listed as Jane in Canadian 1861 census when, living with her parents-in-law.
