Hello Jeffery. As yet I have not made any connection with a Janet Elliot of 1821 but I do have the 1851 Census for Castleton Parish and the nearest in age for Janet is the following:- Newcastleton-Head. James Elliot Unmarried age 35yrs, Mother Margaret Elliot, age 71yrs, Widowed, Sister Janet Elliot age 28yrs, Unmarried. Niece Margaret Nichol age 3yrs. I will give you what Elliots I have that are my ancestors if you wish. Kind regards Carmel
