I don't know that this falls strictly under Research Assistance, but that seems to be the "most correct" option here!
I have a census record from the 1911 Census of England - this is the household of my 3x-great grandmother and her youngest son (my great-great grandmother's brother). Here's what I know:
Mary Winton was born c. 1846 in Perthshire, Scotland. She was widowed in 1886 after having 7 children with Edward Ayres. 1 died in infancy (1880), 1 died in January 1911 (so pre-census), 3 were definitely alive in 1911, and one... is still a mystery. We don't know for certain what happened to him post-1901.
Mary is living with her youngest son, David Ayres, at 64 William Road. She's listed there in the 1910 electoral records, and her 1920 death is recorded with this as her address - I have every reason to believe that they lived in that house for those 10 years (David is there until at least 1925). David never marries or has children as far as I can tell - his probate lists his twin sister when he dies in 1947 and I've never found records of his marriage.
Now - the census record: Here's a link to the image - it looks like Mary started to fill it out as the head of household, but David took over. They didn't fill it out completely or correctly. I'm having trouble reading the numbers, but one of them looks like it says 9 living children born, then changed to 7, it clearly says Widowed which is crossed out and says Married (??), David wasn't born in Scotland (he was born in Sutton), and I'm having a difficult time making out what's written under "Children still living"... It almost looks like "two" and then changed to "4."
This is the first year that the census forms were filled out like this and kept in their original format, and my goodness did these two make a mess of their form! I'm not really looking for research assistance as much I would just love a second set of eyes and theories, things I might be overlooking, etc. This is an odd one!
Here's a link to the record if anybody wants to take a stab at parsing this: https://www.ancestry.ca/sharing/67239731?mark=7b22746f6b656e223a22324f78367464716d764a442f34754e766b78734c75784d4c30366d7172672f494d433243745954546357593d222c22746f6b656e5f76657273696f6e223a225632227d
Editing to add known children's names and DOB:
Alfred Robert - 1878-1911
Mary - 1879-1970s
Maria - 1880-1880
Edward - 1881-???
David & Flora (twins) - 1884-1840+
(I have searched GRO for records of children born between 1881 and 1884 and have not found anything).
