The records are on this site.

If you check the link below it shows Thomas Warren married to Mary Carter. They had a son also Thomas Warren who married Sarah Ann Selwyn. They had a son George Warren who married Charlotte Carter but it states that she was born in 1825 not 1823. This might help or it might confuse you more.
