George, I didn't know that Alexander Traill had a brother, Col. Andrew Traill (1534-1608).Thank you for this information.All the information I have of the earliest Traills isthat Alexander Traill had two sons: (1) George Traill, born in Blebo and died in 1634. He accompanied Earl Robert Stewart to Orkney abt the year 1580 in the capacity of steward or factor.He married twice: (i) Jean Kennedy (of Carmunks), who was a near relation of the Cassilis family.They had 2 children: (a) Col. Thomas (of Holland) Traill, born abt 1600 and established an estate called 'Holland' on Papa Westray. (b) Elspeth Traill, died 1643.She married Edward Pottinger.(ii)Isabel Craigie, with whom he had 13 children.One of them, James (of Westove) Traill, married Jean Cok in 1668 and had 7 children.One of them was William (of Westness and Woodwick) Traill; another was Thomas (of Westove) Traill, who died on 25.10.1689.Thomas married Anna Graham (daughter of Patrick Graham of Grahamshall) on 6.8.1683.They had on child, James (of Westove) Traill, who married Barbara Fea (3rd daughter of James Fea of Clestrain) on 5.12.1712.They had 3 children, the eldest, Thomas (of Westove) Traill married Marion Stewart (daughter of Archibald Stewart of Brugh) on 4.1.1757.They had 8 children; on of them, William Traill was born in 1759.He was on of the passengers on the ship 'Marlborough', who at the age of 15 was bound in 1774 for Savannah in Georgia. (2) Alexander's second son, Col. Andrew Traill, a most distinguished officer, had one son who married Matilda Melville.They had two sons: James Traill, born 1600 and Robert Traill (Lieutenant-Colonel in Cromwell's Army) bor 1603.Robert was a Minister of Elie in Fife and afterwards o the Greatfriars' Church in Edinburgh.A great-greatson of Robert Traill, James Traill, took orders in the Church of England and became Bishop of Down and Connor in 1763. The Australian 'Traills' are descendants of the 'Holland' line.Will this help?, Karl.
