Hello Lynn,

Welcome to the Forum!  

Well the parents and two siblings, Ann & John, are living in the same street in 1901 at number 267. My guess is that she is staying with a friend or relation somewhere and her surname has not been recorded as LONGMORE. You could do a search of other houses in the street looking for an Elizabeth born in 1897, but even if you find one, you still can't be certain without a lot of cross checking. On the face of it, it seems to be a question of incorrect recording. If you find one that meets the criterion and is also a visitor, you may be onto a winner.

Regards,

Maurice
