Thank you very much! this might be her as there is a Malew connection, in that she married someone fron Castletown. I wondered how they met as Kezia was working in Douglas at the age of 18. The Catherine Watterson mentioned is interesting because in 1881 a Catherine Walkington is living in 5 Ronaldway and in 1891 she is living with Kezia, husband and Leslie Walkington Preston, my g'father, in Castletown.
However, I can't see how her father could be Thomas Kelly, when on her marriage certificate he is quite clearly Thomas Cashin! Hmm! I shall have to give this matter some thought. Very many thanks anyway, Jo Swadkin
