Ok ... this is cat among the pigeons stuff! I now have the birth certificate of Frederick William Clare. He was born 20 May 1909 at 8 Dundee Buildings, Clerkenwell, Holborn (There is an earlier post which mentions Dundall Buildings). His father was Frederick Clare, Railway car-man and his mother Annie Clare, nee Sewell. I rather suspect the two were not married. It would appear from court records that Annie's husband, Thomas Murray, did time in HM Prisons. Petty theft. Records state he was aged 19 and a news vendor. Year: 1898 Date: 19 Apr 1898 Court: Clerkenwell Place: London.
