I can't easily see William and Margaret Christie on 1901 which would fit with likely Irish origins. For Elizabeth's parents, there is this possible entry showing in 1901:
James Jamieson 26, shale miner, b. Cowdenbeath, Fifeshire
Agnes Jamieson 25, b. Alloa, Clackmannan
John Jamieson 4, b. Kirknewton, Midlothian
George Jamieson 2, b. Kirknewton, Midlothian
Cathrine Jamieson 3 months, , b. Kirknewton, Midlothian
Isabella Allen 22, cousin, b. Alloa, Clackmannan
Address: 79 Oakbank, Kirknewton and East Calder, Midlothian.
There is a marriage showing in 1896 in Alloa Clackmannan for a James Jamieson and an Agnes Mitchell which might be their given Agnes' birth place showing on the census.
