Hi Kevin,
Tell us about the 1911 Census. We are not allowed to look up 'for you' and post the details - but you can, you are allowed to tell us what you know.
1911: Elizabeth SMITH nee LONGTON
How old is she?
Where is she born?
Where are they?
I see from GRO:
Thomas Longton SMITH birth reg Sep Qtr 1909, Lancaster, mms Longton
Alfred Wells SMITH birth reg. Mar Qtr 1912, Lancaster, mms Longton
Robert SMITH birth reg. Jun Qtr 1914, Lancaster, mms Longton
Taking a punt she died in the Lancaster Registration district between 1914 and 1925, narrows things down a bit:
Elizabeth SMITH:
age 35, Mar Qtr 1916, (b abt 1882)
age 45, Dec Qtr 1916, (b abt 1872)
age 46, Sep Qtr 1921, (b abt 1875)
Which one of those - if any - matches the age she is in 1911?
Cheers
AMBLY
