did George have a middle name ??
George William Pritchard and Bertha have 3 children
1898 in Bath ,Somerset - Archie G Pritchard - in 1901 they are in Stalybridge ,Cheshire
1902 christened 9th March at Castle Hall, Cheshire - Bertha Pritchard
1904 christened 11th March at Castle Hall ,Cheshire - Georgia Clarissa Pritchard
if it is a possible
Bertha Pritchard married Richard Harlow at St Peters Catholic church 29th October 1927 Stalybridge ,Cheshire ......so I presume Castle Hall is near or in Stalybridge ??
just googled - Castle Hall was the name of Holy Trinity church in Stalybridge .
so - if we do have the right couple - they went from Liverpool 1890's to Bath then 3 years later to Stalybridge ,Cheshire ....I wonder if George was in Service ....see if you can find him in 1901 census in Bath or Stalybridge for his occupation
its all I could find to be a possible for your George and Bertha
sadly ....
http://www.lancashirebmd.org.uk/cgi/marrind.cgi just has George Pritchard on the marriage record ... I will see if there is another George W Pritchard and Bertha marriage
