I guess I’ll need to double back on people I’m missing and try to see if somebody fits year wise rather than solely looking for listings with the mother’s maiden name. Would explain why I can’t find them.
Until the Covid pandemic, mothers' maiden surnames were only indexed for births from 1929 onwards, but during the pandemic large numbers of mothers' maiden surnames were added to the index. I believe the project to add mothers' maiden surnames to all post-1855 births in the index is continuing.
This explains why
scottishlad failed to find the birth he was originally looking for.
I note with interest that his Agnes McKenzie's mother's maiden surname is one of those yet to be added to the index.
