Hi Monica
I used to access Ancestry through the library, but have not been able to do so during the lockdown.
I have followed this up and found a 1901, 1911 census and a death certificate for Annie which shows she died in the poorhouse. The 1911 census shows she had 8 children, 7 alive, I however can only find 7 children in total and there were only 6 on the 1911 census which did not make sense so I will need to investigate further.
I have also managed to find spouse's for all her children, so I can no work on these. So thank you for pointing me in the right direction.
I will get back to you on Agnes and Margaret tomorrow, as it is getting late now,
