Hi Koromo
Because they were a theatrical family, it would be quite understandable that stage names were used - which may be completely made-up or a combination of true & made-up - and appear in some records rather than their birth names.
?........Maybe it went this way:
Margaret M A W Lewis age 24, is lodging with the man she was to shortly marry - Edwin W. BRETTON .
His middle name is probably Whittaker and that is probably his real surname. Edwin is probably an anglicised version of his real Welsh forename and probably, for the times, the English version was more acceptable in his profession.
The marriage is in his real surname but his adopted first name.
His son is named after his real name first & last........?
In Census 1901 Edwin & Margaret are vistors to a family named Scott:
At least it appears your couple did not fudge their ages, even if he mucked about with his name
Note 1901 Census states Edwin was born in Wales, not Yorkshire.
But Cullingworth appears to be in West Yorkshire.......hmmmm??

This may be Nora's FREEBMD Birth - under her father's real surname:
Births Dec 1896 District: Stockport 8a 31
Whittaker Nora If they are keeping the official births of children under real surname, then there is the following birth also, which may tie in (searched all births for "Surname: Whittaker/ First name: Cec" - this was the only girl result):-
Births Jun 1893 District Manchester 8d 225
Whittaker Cecilia Hannah Probably given you more questions
, but hope it may help!
