Thank you for these - I have found further info which confuses/puts doubt into some of the suggestions.
I have Mary Maddick born to Jane Lillicrap 6/1842 Plympton St Mary Union. She'd married Robert Maddick 6/1842. However, MARY ANN Maddick marries William Mitchell in 9/1845.....youngest Mary dies 12/1844??
I have William Henry Mitchell born 6/1850 mmn Lilycrap.
