I have my ancestor Mrs Wilkes born 1856 living Southwark in 1911 census
with her children Grace Violet 1890, Leonard Ernest 1891 ect.
Is Mrs a widow please.
I have her 1901 census with her husband Lawrence
and have the marriage certificate for some of the children 1914
where they state Lawrence is deceased but I cannot find his
death details.
Many thanks Irene
