Helen, thanks for the information.
I did have the 1901 entry for Isobella & family, BUT my husbands family INSIST she was born in Scotland!!!.
I am almost sure that the 1901 entry is correct family (but we all know that sometimes what is written on census returns is not always correct - eg. born in wheatley hills).
If you have the 1891census for this Isobella and it states that neither her or her family were born in Scotland, I think that has to pretty much squash that theory.
Would there be any chance you could send me all the details of that entry for 1891??. I would love to find details of her parents / siblings / ANYTHING..... It would be a great help to me.
Again, a very big thank you for your time & effort. Yours, Carol..
