is she deceased? i found her birth, i wont put it on here as its less than 100 years old
there appears to be 3 children born in the Epping district between 1919 & 1927 with same mmn. as you said
which leads to the marriage (as you said) :
Name: Horace F Shepherd
Spouse Surname: Grainger
Date of Registration: Jan-Feb-Mar 1919
Registration district: West Ham
Inferred County: Essex
Volume Number: 4a
Page Number: 220
i think you can bypass her birth certificate and get the marriage certificate this will give you Horaces father name and hopefully you are on the right track
