Hi Circam
Thanks very much for that information.  My line comes down through Archibald Morrison and Elisabeth Tosh/McIntosh. I have been at an impasse for some time. I have been unable to find Archibald's death registration. ( His last census entry is for1891 aged 79, born Inveresk, ML.  His birth is elusive also.)
Like you I have Elizabeth's death registration, but have only recently obtained it which helped no end.
I'll spend a bit of time looking over the content of your message, thanks once more.
Tom
