have you looked for Christina Florence Wilson in 1881/1891 + 1901 - have you also looked at the newspapers I suggested which mention an unmistakeable Scots accent as well as a throwaway line that she had a bad reputation - thus some personal research in the Police records held at Manx Museum might be useful
in 1881 I can see a 16yr old Christina Wilson living with gparents Montcrieff in Perth at a place called Milton Bog - all around were flax weavers which may just possibly be a link to IoM via Tromode
