John Alexander of Scotland 1685 & daughter Ruth who married James Thompson

I am trying to determine the validity and gather sources for the following family story.I would like to here from any descendants of the John Alexander or James or Alexander Thompson mentioned in the stories below.

John Alexander (from Scotland, possibly from Lanarkshire), his wife (no name given) & his daughter Ruth emigrated to Philadelphia PA before 1739 according to "A Dictionary of Scottish Emigrants to the USA", Volume 2, compiled by Donald Whyte.Published in 1986 by Magna Carta Book Company.Family story says James Thompson emigrated with them but I cannot find an emigration source for him.

James "Jimmie" Thompson was orphaned at age 10 in Ulster Province, Antrim county, Ireland. He was bound to Patrick Hagan. Hagan was a harsh task master and made Jimmie do most of the farm work. Sundays were spent in religious study at the Hagan home. Jimmie Thompson ran away from Hagan when he was 13. He crossed the sea into Scotland with a merchant friend. He met a John Alexander who hired
James Thompson to plow for him. The Alexanders were Presbyterians and they took Jimmie into their home and reared him. He was sent to his first formal school. John Alexander had one child, a daughter Ruth. Jimmie fell in love with Ruth and they wanted to marry. Her parents did not allow this until Ruth Was 18 and Jimmie was 21.

The John Alexander and James Thompson Families emigrated from Scotland to America in the 1730's. They settled about 20 miles west of Philadelphia, Pennsylvania.

Some family trees show Ruth and Jimmie did not marry until they reached Pennsylvania in the USA.

James & Ruth had at least 6 children, 1 daughter and 5 sons.Alexander Thompson move from PA to Burke County NC where he participated in the Revolutionary War as a Private in Continental Line in Battle of Kings Mountain North Carolina. Wounded and recieved land grant in Georgia. (LSDAR Genealogy Forms, Vol V - 1961, p 233-234 & 530.)Alexander Thompson 1739-1815 died in Madison County GA.

James Thompson's father, John Thompson, whose ancestors had moved from Scotland to Ulster Province Ireland, married Esther Hale in Ireland. A horse ran away with him, throwing him over a bluff, killing him instantly. In a few days his widow died, leaving an only child, James, then ten years of age. ("THE THOMPSON FAMILY" from the American Gen. Research Institute, Arlington, VA copyright 1972)

According to an article written by Calvin G. Floyd for the
Danielsville Monitor in May of 1978, he indicates that John Thompson was Scotch in ancestry and that Esther Hale was Irish in ancestry. The article further states that John Thompson was the son of Capt. Alexander Thompson who lived in Scotland and that Capt. Alexander Thompson's father was also named Alexander.Capt. Alexander Thompson served in the Tyrone Rebellion and was given a land grant in Ulster Ireland where he moved.

There is a problem with dates in the Alexander Thompson story.The Tyrone Rebellion dates to approximately 1594-1603.This is too early to be either of these Alexander Thompson's.I would like to see the land grant document for the land in Ulster or at least an index listing.

Any help, comments, or information pertaining to these family stories would be much appreciated.
