My g Grandad was Herman Frederick Phillips born 23/02/1886, that's his name on his marriage certificates 1905, 1912 but on his pension records from WW1 he is known as Frederick Phillips born in england 23/02/1886, so I looked up birth records for the first quarter of 1886 and found 4 fredericks all born in march and 1 Herman born in feb so ordered birth certificate and the birth date matched 23/02/1886,mother was Lizzie Phillips,place of birth Pancras workhouse but no fathers name, but his fathers name was on his marriage cert Herman H Phillips, I am so confused can anyone help shed some light on the change of name and the fact that his fathers name is not on birth cert. I can't find them in any census either. thank you
