There is a Phillips inquiry in this month's WDYTYA Magazine at this link. Thanks to Debbie Kennett for this tip. Here is the text:
"My great grandfather was born on 23 February 1886 in St Pancras Workhouse. Named as Herman Phillips, the mother's name on the birth certificate is Lizzie Phillips of 22 Percy Street, Camden. I have been told that this was a boarding house/hotel.
I have found Herman's birth and baptism in the workhouse records, and I have also found a Eliza Phillips being admitted on the day Herman was born. She was discharged on the 13 March 1886.
I cannot seem to find Herman Phillips or his mother in the 1891 or 1901 census, although he does appear in 1911.
But this is where is gets strange. His birth certificate gives his name as Herman Phillips, his two marriage and death certificates say Herman Frederick Phillips and his First World War service records all state his name as Frederick Phillips.
Does anyone know whether I could find out a bit more about his mother and whether they would appear on the 1891 or 1901 census?"
