There seems to be a bit of confusion with the responses to your enquiry?According to my records it is possibble that your 3x gt grandmother ,Catherine ,may be the sister of my 2x Gt grandfather,William Corlett born 1815
If could supply more of 'your own information'on her (sisters,brothers,dates etc) then I will check my records to see if I can clear it up.You should be aware that there are a lot of similar named(catherine ,Jane Corletts) families within that time/ area.
