It is very easy to get distracted from the main lines of research and shunted off on to sidelines, but it is also fun. My Scottish relatives are currently intriguing me with a question as to whether their Greig lines might have a connection to Edvard Grieg. A hop over the North Sea and a variant spelling, but not impossible as he did have Scottish forbears. Perhaps unlikely though as there were many Greigs in Scotland at the time. Nevertheless a fun theory to dabble with.
