baptised "... May 28th (YEAR?) witness George Argo ..."
I can see a "George Argo, Cairdseat" in the Aberdeen Journal, 19 Dec 1832 and a "George Argo, Tarves" in the 3 Nov 1847 edition.
There's a Cairdseat farmhouse near Ellon.
What was the baptismal year?
As an aside - in a 1946 newspaper article, headed "Family Tree Detectives " it explained how they began with the clue "Causeway end 16 Nov 1719 at Hether Canchrie" and eventually found the birth details under "Cassie-end, Nether Banchory". (Only reference to "Cassie-end " I can spot).
