Its interesting as bapts East Dereham, Mother MARY Eke;

JANE 14 Mar 1819, birth 3 Dec 1818
MARY ANNE 23 Dec 1820, birth 4 Dec 1820
Also a burial DAVID Eke 11 Dec 1808 age 23, A Married Man. Stated As David EKE Junr.
David EKE married Mary BLADE 20 Oct 1806, bachelor/spinster
They had children;
JAMES bapt 10 Mar 1807
MARY ANN bapt 15 Jul 1808 (cant see burial for her)
So just a possible for Mary Turner/Eke
Trish

EDIT looks possible as a Mary BLADE was bapt 31 Mar 1785 to CHRISTOPHER/JANE
So would make her 44 if she had a Son John c 1829
