Frances, long time since I've seen/heard the expression "sooth moother" as I was referred to when I was up visiting the in-laws.
Regarding the "Shetland" flag I recently attended a Shetland family history society meeting in South Shields and the "Shetland " flag was there in abundance.
How and when it came into being I don't know, it seems fairly new to me, it would be nice to know from whence it came. Rhoda was given a "Shetland" flag lapel badge by our son who knew more than his mother as to the significance of it.
