The children of John MITCHELL and Jean CLUGSTON were William 1820, Mary 1822, James 1825, John 1827 and Jean 1830.
Is your John the one in Barony in 1841 with an unnamed female MITCHELL aged 48, Jean 16, Barbra 14, Agnes 9, all with the surname MITCHELL? In 1851 he is in Calton with Jean CAMERON 58, Barbra CAMERON 24, and Agnes CAMERON 19.
Wouldn't these probably be the children of Jean CAMERON and you need to find Jean CLUGSTON/MITCHELL, hopefully with at least a couple of her own children in 1841 and 1851?
