There are a few reasons why a case that began in Fife could have gone to Edinburgh. It could be that the father lived in Edinburgh and the case should therefore have been heard in Edinburgh, not Fife.
When you say to ‘went to Edinburgh’ though, did you mean it went to the Sheriff Court there or did it go to a higher court or a different type of court in Edinburgh? As your case was before 1830 it may have been heard by the Commissary Court.
Here’s a quote from the book “Tracing Your Scottish Ancestors” which is published by the National Records of Scotland (8.20)
“The divorce and other consistorial cases heard by the Commissary Court in Edinburgh cover all aspects of marriage, separation, divorce and legitimacy, yielding a profusion of detail about marital and domestic circumstances.”
I must state I am no expert on the Commissary Court and cannot give you a clear outline but it would seem that before 1830 some cases were heard by the Sheriff Court and some by the Commissary Court.
If you would like to email the details to us we can try and help you unravel the situation in your case.
The good news is that there is an index to some (not sure on coverage) Fife Sheriff Court Decrees is available from the Fife family history society. Also “The Commissariot of Edinburgh, Consistorial processes and decreets 1658-1800.” You can view this online. I would speculate that it may be from one of these sources that your relative managed to access the information.
I would definitely recommend the book “Tracing Your Scottish Ancestors” if you are getting into this type of record as it’s a wonderful reference book. It will be one of our May prizes for our ‘Then & Now’ (
