Hi Hil
A parent search on the IGI give the following children to James Ross and Elizabeth Sutherland. I'm pretty sure this is the same family you have on the 1871 census and might even suggest that Johan might be on the census as Jean?.....Georgina and James certainly fit. As well as the large gap in ages beween Helen and Jean where it would be convenient to slip in two more babies...maybe Mary and Elizabeth?....and Mary being born in 1855 would tell you how many other babies the couple had. You would have to work a bit to figure out if Besy fits with this family or not but their marriage in 1842 would certainly tie in well with her DOB.

Also interesting to note the two adjacent Ross families on the 1871 census page.....maybe another generation?
My money is riding on this George being yours.
