Please could someone date this family portrait

Hi all
Please could someone date this photo. I am told that it is possibly ancestors of my husbands, and the family that I am told it is, the children's names that I have from censuses don't fit the ages and sexes of the children in the photo.  If it was dated it may help determining who they could or couldn't be. 
Many thanks for any help.

1900-05.The pigeon-front blouses of mother & daughter were popular at this time.
You need to look in the 1901 census.
The children look to range from 3 - 15.
Be aware this may be a second marriage so the children may come from different families also these were given to friends so may not be family at all.

Thank you Jim.  That rules out the family I was told it might be, as the date of birth for the eldest child was 1906. That would estimate the photo, going by the ages you give at about 1921.
Thanks for your help Jim, much appreciated
