Hi Lex,
What are the ages of the children who are alive at the time and on the 1911 Census? How many children are stated on the 1911 as being born to the marriage? Rootschat rules say we can't look this data up and post about it, but if you already have that information, you can post it up to tell us about it!
On the 1911 Census, the question is about children - born, living and dead - to the marriage. If William was not James' natural son, technically he shouldn't be included in the list of children born (living or dead), of the marriage. (Of course this rule was not always correctly followed by the households filling in the Census paper - however:
I can see the following children:
BIRTHS:
James Arthur 1898, Camberwell )
Alfred Hoyden 1902 Woolwich
Alice Colinda 1904 Woolwich
Constance Phyllis 1906 Woolwich
Gladys Caroline 1908 Woolwich
Hilda M 1911 , mms DUNKIN (registered Dec Qtr Woolwich - probably born after Census?)
And deaths before 1911:
Alfred Hoyde_ age 2, registered Woolwich, Jun Qtr 1904
Edward Ernest age 1, registered Woolwich, Dec Qtr 1910
That looks like the two deaths?
Which still leaves William unaccounted for between 1901 & 1911.
Cheers
