This person is the mother recorded on the burial record for Sarah Ann Brown Neech (see below). Neech may have been Delannia's mothers' married name, wife of Thomas William Neech. Thomas was deceased well before the daughter Sarah was born which may be why only the mother's name is recorded in the register?
