It's difficult with it being 1908 - you could do a 1911 address search for 8 Trinity Road East Finchley perhaps.
1901 RG13; Piece: 1234; Folio: 107; Page: 28
has a Wightman family living there who all seem to be born around the area.
However, there is a Mary Jackson b 1838 Nottingham there too- a monthly nurse. Could be a big red herring

because she is 63 yrs and this is 7 years earlier.
