Flogged not Flagged,; anyhoo,
all from c1660 to 1900 were FREER, begining with George Freer, ordained minister at Lethendy, married Helen Blair 26 Dec 1699, my line is of 1st son Adam Freer 1704, but going the other way, Helen Blair's father was John Blair 8th of Ardblair, John Blair married Isabel Stewart daughter of James Stewart 1st of Ladywell.
Also given the name of Stewart of Garth,
James Stewart of Fincastle, I have little on dates and location, only names at present, confirmed by Stewart Society and Gordon Macgregor.
