Found them at Anc'y in 1911 in Winnipeg by searching for Annie by birth details.
I don't have a sub for Canada so can only report what the free search says.
William S Maskell 1863
Annie Maskell 1865
Maskells in the 1911 with parents Annie and William S:
James A 1893
Margaret 1803
Walter 1906
Francis Billepen 1885
- i.e. married daughter living with them - others with that surname are:
husband Garriet 1878
daughter Maria 1910
Now if we had a clue who "Garriet Billepen" really was ...
Yay. At AG they are listed as
Maskell (?) William S, 48 (May 1863), occupation Dept Store, at 407 Sherbrooke
Maskell (?) Annie, 45 (Jul 1865)
Maskell (?) James A, 17 (Mar 1895)
?askell ? Margaret, 8 (Mar 1903)
?askell ? Walter, 4 (Nov 1906)
Bellefeu (?) Francis, 25 (Aug 1885)
Bellefeu (?) Gabriel, 32 (Dec 1878) (son-in-law)
Bellefeu (?) Marian A, 1 (Apr 1910) (granddaughter)
http://automatedgenealogy.com/census11/SplitView.jsp?id=34281(to find them at AG, you have to search for surname Maskell and then merge the "Maskell (?)" soundex surname)
And finally, a birth registration:
http://vitalstats.gov.mb.ca/Query.phpWalter Gerald MARSKELL
dob 30.11.1906, St Boniface (Winnipeg)
and
Margaret Josephine MASKELL
dob 14.03.1903, Winnipeg
Why the apparent surname change -- or were all the examples of Marshall wrongly transcribed?
But a father William who is a tailor, with son William virtually exactly the right age ...
Frances MARSKELL married Gabriel Bellefeuille 16 Aug 1905 in Winnipeg.
Two other Marskell marriage in Manitoba:
Phillip Wm in 1905 to Agnes Murray
William in 1910 to Minnie Edwards
Hmm.
A William Samuel Marskell was reg in Sep quarter 1863 in Romford.
But argh, in 1891 he was in England.

and
William MAISKELL (obviously mistranscribed)
