Son: Walter Odaver aged 5 born Windsor

Maria Noakes aged 74 born Cookham Berkshire
Looking for the birth registrations for the above children I have found these:
ROWLES, ESTHER mother's maiden name
HOPSON GRO Reference: 1842 D Quarter in NEWBURY Volume 06 Page 197
ROWLES, JOHN BRICE mother's maiden name
HOPSON GRO Reference: 1848 J Quarter in READING Volume 06 Page 243

ROWLES, GERTRUDE FANNY mother's maiden name
WILLIS GRO Reference: 1860 D Quarter in WINDSOR Volume 02C Page 361
There was this death which could be Esther Rowles mistranscribed as Hester:
ROWLES, HESTER aged 24
GRO Reference: 1849 S Quarter in READING Volume 06 Page 170
and this possible 2nd marriage for John Adams Rowles:
Marriages Jun 1853
Giles Mary Ann Newbury 2c 355
Moulding Sarah Newbury 2c 355 <<<<<<
Pocock Thomas Newbury 2c 355
ROWLES John Adams Newbury 2c 355 <<<<<<<
Tracing Sarah back there is this possible marriage:
Marriages Dec 1848
Challis Livinia Newbury 6 449
CLACK Charlotte Newbury 6 449
Cooper John Newbury 6 449
CRUSE Ann Newbury 6 449
MOULDING John Newbury 6 449 <<<<<<<<<<<<<<

son for this couple:
MOULDING, WILLIAM HENRY mother's maiden name WILLIS
GRO Reference: 1850 M Quarter in NEWBURY Volume 06 Page 235
Death for Sarah's husband John:
MOULDING, JOHN Aged 24
GRO Reference: 1850 J Quarter in NEWBURY Volume 06 Page 152
1851 census:
Abode: St Nicolas Newbury Berkshire
Sarah Moulding, aged 25, Widow, born Greenham Berkshire
William H Moulding aged 1 born Newbury
As the 1861 census doesn't actually state what relationship Maria Noakes was to John Adams Rowles but assuming that she was Sarah's mother perhaps John registered the birth of Walter in 1856 thinking that Sarah's maiden name was Noakes and not Wiiis
It's possible that Thomas Benjamin Rowles married in 1848:
Marriages Dec 1848
CROOK William Totnes 9 605
DOLTON Eliza Totnes 9 605
Fogwill Eleanor Totnes 9 605
HOLMAN James Totnes 9 605
LIZARD Harriet Totnes 9 605 <<<<<<<<<<<<<
Rowles Thomas Benjamin Totnes 9 605 <<<<<<<<<<<<<<<
possible birth for a daughter;
ROWLES, CAROLINE LIZARD mother's maiden name LIZARD
GRO Reference: 1849 S Quarter in NEWBURY Volume 06 Page 207
