The first of the name who settled at Ballyrilland, Baloo, was David Girvan. He came from Girvan in Ayrshire at the plantation of Ulster in the year 1606.
His son, also named David, helped to build a ship to take 100 Presbyterian families to America, persecution still raging strong in Ulster. The ship was named the "Eagle Wing", from that beautiful passage in the book of Exodus, when the Lord talked with Moses. The "Eagle Wing" set sail from Carrickfergus on the 9th September, 1636. She was turned by tempestuous winds, and well for the Protestant cause it happened so. This David Girvan married Mary Moore of the same place.
Their son, John Girvan, married his cousin Mary Moore. He was a notable man in his day, was bailiff of the parish, and was a great friend of the Downshire family of Hill, which at the time owned Raloo. In fact, Lord Downshire made John Girvan's youngest brother David, manager of one of his Tullylish Mills on the River Bann. He amassed a large amount of money which enriched many of his relations. The letters of this John's name and date are yet to be seen on a stone in the old homestead, at present the residence of Mr. Hugh Crawford.
James Girvan, son of this John, married Annie Donald, and their son David Girvan married Mary Long of Islandmagee, and their son William Girvan married Jane McDowell from near Woodburn.
Their son David, married Mary Clements of Ballysnod. This Mary Clements was descended from Henry Clements, an English man who got a Grant of the Curran of Larne from King John in 1210. She was also descended from another Henry Clements who was Mayor of Carrickfergus, and on the Houston side she descended from Captain John Houston of Ballyboley, a soldier in Cromwell's Army, who, on 17th April, 1648, married Margaret, daughter of James Shaw and his wife Isabella Brisbane of Ballygally Castle. Mary Clements was also a blood relation to Sir Houston Smiley of Drumalis, Larne, and her mother, Agnes Snoddy's ancestors, came from Cantyre in the train of Randal McDonald, first Earl of Antrim, and her ancestor, Robert Snoddy of Carnduff, was paying Hearth Tax in the year 1669.
