I'm also at the brick wall with "my" Orwell, Kinross Guthrie person. So, I'm looking for other Guthrie people from Orwell in the hopes that we can piece together some Guthrie families. I have a Margaret Guthrie (b. 1811) who married Walter Trotter 1833 in Auchterderran Parish, Fife. The marriage notation states that Margaret was from Orwell Parish. It seems that Orwell Parish records are bleak- sporadically kept at certain times and with missing time periods.
On another note, I see the Gow and Low names in the book, "Auchterderran: A Parish History" [available and searchable on ancestry.com- proprietors of some land in Auchterderran. Sincerely, Rea Trotter
