Have to admit the location is not good for the DC I found and JJeanie followed up on......but there is no DC recorded for any other *ath* McK*n Noble after 1855.
So I guess now try and trace foward the Katherine you've found...and also try and figure out if those people in the Cambuslang household of 1881 will fit into the family somehow
Still thinking on this one.....
Best wishes
Jean
