Hi again, it was only by chance in the search for a baptism for Rebecca I located this:-
Herbert Pickering b 5th August 1900 baptism 14th October 1901 Father Emmanuel occ Weaver Mother Ann abode 6, Alma Street
The GRO Index shows the mmn of Herbert was HODGSON
In 1901 census is an Ann Pickering 24 Married with a son Herbert aged 7 months with her Hodgson parents at 5, Higson Street, Blackburn
Census ref RG13/3909/64/25
Is this another Emmanuel/Ann who married June 1900 Blackburn 8c 723?
Keyboard86
EDIT believe this Emmanuel was b c 1872 so back to drawing board!
Where did Mary & Rebecca get such a markedly different ( Maiden name ) at their respective marriages eg MERRICK?
