Hello again, Bones,
You will have noticed that I have continued with my research which coincides with your comments about DAVID TRAIL.
As I see it, David TRAIL married Ann MELDRUM on the 27th October, 1827 at Scoonie and they named their eldest daughter, Agnes Swan TRAIL who was born in August 1828 at Scoonie. One of her sisters was indeed Elizabeth TRAIL, born 12th January, 1836 and yes, she went on to marry William COWAN in 1858 at Scoonie.
You are quite correct about David's father, being James TRAIL. He married a lady by the name of Elizabeth DOWIE on the 3rd of December, 1790 at Kettle. In my latest postings, I explain that the farm where I lived at the end of World War II - Easter Lathrisk Farm explains the ancient name of the village of KETTLE. Lathrisk was the original name for the village.
Do you have any further information about David TRAIL's wife, Ann MELDRUM?
You may find it interesting that William COWAN's sister-in-law was Agnes Swan TRAIL and that she was born in Scoonie. However, you may also be interested to learn that there was also a Janet Swan MELDRUM, who was born on 7th March, 1813 also AT SCOONIE. Janet's parents were David MELDRUM and Agnes WILSON. As you can see from this, the COWANS, TRAILS, MELDRUM's and WILSON's were all living in a pretty small area of Fife and so it may be worthwhile to follow those leads.
Kind Regards,
Tom.
