In the 1911 census the information was provided that she was 34 and born in Co Carlow, Ireland.  This gives a birth year of 1877, but I can find nothing in the censuses of 1881 or 1891 to confirm this.

On the other hand she married Philip Bryant in 1893.  If she had been 18, this would have given a birth year of 1875.

In one report of the divorce case, it is said that she had been a friend of a sister to her future husband, so she must have lived in that area in 1893 or before.  But she is not to be found in Devon or Cornwall in the 1891 census as Lilla Burton.

I think the marriage certificate for her marriage to Philip Bryant might show something of her age and father’s name.
