Just do a Google search for Aitken Fyall and you will get several hits for his book.
East Neuk families can be difficult to research as so many people have the same names and cousins and second-cousins marry (I suspect I'm preaching to the converted on this thread!).
I always have to be careful to distinguish between Robert Allan and Agnes Meldrum who were married in 1817 in St. Monans, and Robert Allan and Agnes Meldrum who were married in 1827 in Elie but ended up living in St. Monans. The two women were related, and both relate to me on my grandmother Watson's side.
And just to stir the pot a bit more, the Robert Allan and Agnes Meldrum married in 1827 had a son, William Meldrum Allan, who married Elizabeth Watson of Cellardyke, a sister of my great-grandfather Watson! (Pictured left as my male avatar with his wife and distant cousin Margaret Watson).
