No, Mr R, not Walter: several well-loved characters have had their actors replaced--not always successfully; remember Frank Middlemass as Dan Archer?--through death, conflicting professional demands, or plain old-fahsioned walking out: like Heather Bell (Clarry), who left in a dudgeon becase they wouldn't give her time off from rehearsals to go to Haydn Jones' (Joe Grundy) funeral.

"Mrs P, ma'am" was indeed Mrs Perkins, Peggy, Jill and Jennifer's mother. They were evacuated from the East End of London in the war, and stayed; Peggy married Jack, Jill married Phil, and Jennifer married that wicked capitalist and philanderer Brain Aldridge. Sid Perks came from Birmingham with Jack Woolley, I think, who moved in from Stirchley.

And of course, Aunt Laura (remember her at Ambridge Hall?) came from New Zealand, where Dan and Jack's brother (name??) had emigrated years before to raise sheep; I think she was his daughter, but I never quite worked it out.
