Think this MAY be our man given the birthplace and age ?

1911 Abercarn, Abercarn, Monmouthshire, England
Household Role Sex Age Birthplace
Ernest Pritchard Head M 37 Assorter. Trelleck, Monmouthshire
Agnes Pritchard Wife F 29 Aberdare, Glamorganshire

Surname First name(s) Age District Vol Page
Marriages Dec 1909 (>99%)
COOPER Esther Newport M 11a 420
JOHNSTON Agnes Newport, M. 11a 420
PRITCHARD Ernest James Newport M 11a 420
VENN James Newport M 11a 420

Several Agnes Pritchards in FreeBMD records, but IF this is Earnest's wife ?... the age fits compared to the 1911 Census, it also fits his re-marriage in 1929.

Deaths Mar 1927 (>99%)
Pritchard Agnes R 45 Newport M 11a 399

Luckily post 1911 Birth records give mother's surname as well as father's.

So from FreeBMD, their children may include;

Surname First name(s) Mother District Vol Page
Births Sep 1911
PRITCHARD Edna M Johnston Newport M 11a 629

Births Mar 1913
Pritchard Ernest R Johnston Newport M. 11a 634

Searching for marriages for these two, cannot see any obvious links to the FoD.

So was this "our man" or not ???
