Which is ironic as they have been "mongrels" far longer than we have (as my new signature suggests!). There is a fundamental difference though. Inverness Thistle (who are also a previous merger of themselves, Crown and Union) and Caledonian merged to form Caledonian Thistle in order to join the Scottish Football Leagues. Dingwall United Victoria and Dingwall Thistle were two tiny provincial clubs who had to merge together to a former another tiny provincial team in order to join the big fancy Highland League (they somehow managed to gain a license to play in it's inaugural season in 1893 but had to resign - how embarrassing!). They then merged proper in 1929, to form the glorified Muir of Ord Rovers that we all know today (they also had to change their original name from "Dingwall Victors" to "Ross County", probably to gather more support!).
