The BAIN descendants chart has been republished to include a few more of the family of Catherine McKENZIE and James SHEARER who emigrated to Toronto in 1887/8.
I've just noticed that she has never been included in my WorldConnect db LornaHenderson, so this will be remedied next update (dtr of Janet BAIN and James McKENZIE Clashmaharribeg, Lybster).
Still two of them to be accounted for, a Lizzie found in the 1881 census but not later (and there was an Elizabeth Jane born several years later in Canada), and identification of the informant for Catherine's death.
By elimination she is probably dtr Janet as Mrs James BRUCE, but I haven't found her marriage as yet. Whichever daughter she was, she was living at 96A Ashburnham Rd Toronto in Jul 1929.
