This is the best I can come up with -
may be a complete red herring
1901
28 The Shore , Northfleet
John Deadman 38 chalk quarryman
Louisa 34
George Webster son 14
Thomas Deaman 12
Arthur Deadman 10
Lucy Deadman 7
Alice Deadman 5
Bill Deadman 5 mths
That would mean Lucy was his sister not his mother, and that he started life as a Webster, even if he took the name Deadman later! (think he is Deadman on next census)
As I say, may not be connected.
