Marriage 1880 for William Davidson (middle initial "P" not included) & Grace MacDonald in Angus, Scotland on SP.
I didn't search for an area but it was not in Dundee although in the County of Angus which is a fairly large County which includes Dundee & surrounding areas.
That 1880 marriage was in St Mary which is now part of Dundee.
St Mary was always part of Dundee, along with St Clement, St Mary and St Peter.
You would think, wouldn't you, that if you search in 'Dundee', you would get results from all the Registration Districts that make up Dundee (and similarly with other cities where there are several RDs, like Aberdeen, Edinburgh and Glasgow)? You would be wrong.
If you restrict your search to 'Dundee' you only get results from RDs whose official names include the name of the city:
Dundee Burgh, 1st district 1855-1855 (District Number 282/1)
Dundee East and West 1967-1976 (282 then 350)
Dundee 1977 to date (350)
Dundee Landward, 1st District 1855-1855 (282/1)
Dundee 1st, 2nd and 3rd (or Lochee) 1855-1867 (282/1, 282/2 and 282/3)
Dundee East 1952-1966 (282/1)
Dundee West 1952-1966 (282/2)
Just for the record, the differently named RDs in the city were as follows
St Andrew 1868-1951 (282/4 then 282/3)
St Clement 1868-1951 (282/3 then 282/2)
St Mary 1868-1918 (282/2)
St Peter 1868-1918 (282/1)
St Mary and St Peter (combined) 1919-1951 (282/1)
Lochee 1868-1976 (282/5, then 282/4, then 282/3, then 355)
