Valda,
On the freeBMD site there is a referencce of 3a,680 for the marriage of Charles Samuel Catherall and Lilian SemmOns, since these records are typwritten can we assume that they were transcribed wrongly then? as I would have to let the site know if that is the case?
I agree there are many different spellings of names which can make it difficult to trace distant ancestors and easily go off track into a totally different family.
Lilian was age 19 shen she married in 1900 and was therefore born in 1881(3a,257) and is clearly shown in the 1901 census as living with her husband Charles, then aged 23 at 112 Somerset road, Tottenham, one of the boarders listed was 'Lloyd Wallis' who was married to Charles Catheralls sister Rosina in 1902, (3a,228).(by way of further verification).
She died age 67
