Bert,

The Princess Alice was rebuilt in the same location and is still a geogrphical marker for London Transport.

Schantieman, the Eagle & Child is from the arms of the Stanley family who were Earls of Derby. There are several pubs near me named after them, The Eagle & Child, Forest Gate, The Lord Stanley and the Earl Derby (aka The Banjo House) in Plaistow and I think the Eagle at Snaresbrook was originally an Eagle & Child. The family owned quite a bit of land in the area when the pubs were built.

The story is that a child was dropped by an eagle and adopted into the family.
