My Father was adopted by the Kingman family when he was 5 months old and they lived in Staples Rents, Bermondsey. His birth was not registered. How did he get his surname of Tierney? He had a brother called Edward Tierney born 1890. The nearest possibility is a lady named Cool or Coot who lived in 234 Alderminster Road, Bermondsey and we know he was born in that road. Any suggestions as to where the name came from would be welcome. Thank you.
