I have see this on the 1850 census. The elderly lady is Nancy NELSON. It was thought that Emmeline was her daughter. Do You have info on this Emmeline being a Bolton? Isaac is not listed on the 1860 census. and Emmeline is married to James A BRAYNON. The Branyon family reseacher listed Emmmeline's maiden name as Nelson. I am tring to find my NELSON line and have looked over this info. Hope this helps.
