Hard search for Jessie. Not surprised you are banging your head a bit/lot on her searches...
Assuming we have her correctly in that 1891 census entry mentioned earlier, this could fit for her in 1881:
Jessie McLauchlan, 14, domestic servant born Cromdale, Elginshire
She is working at the McGregor household in Wester Cotterton, Cromdale, Moray.
