Brian, there seems to be 2 Jane CORLETT's born in German in 1796 according to the 1841 census I'm looking at on ancestry.com.

My Jane is living at 'Ballacross' with a Patrick CARAN, 25, nailer; Margaret CLARK, 60 (Janes' elder sister); Jane, age 45; and Margaret's granddaughter Margaret CLARK, age 12.
