Where do you think Fleance went in 'Macbeth'?

Fleance escaped while his father, Banquo, died from having his throat slit by the three hired murderers of Macbeth [d. August 15, 1057]. William Shakespeare [Baptized April 26, 1564-April 23, 1616] relied upon one historical source for plays such as 'Macbeth'. That source was 'The Chronicles of England, Scotland, and Ireland' [revised second edition, 1587] by Raphael Holinshed [d. c. 1580]. According to Holinshed's Chronicles, Fleance escaped to Wales. There, he married Nesta verch Gruffydd, the daughter of Gruffydd ap Llywelyn [c. 1007-August 5, 1063], the last native Prince of Wales and the ruler of all Wales the last eight years of his life. Their son Walter ultimately relocated to Scotland, where he became the Royal Steward to the monarchs. He also became the ancestor to King James [June 19, 1566-March 27, 1625] I of England and Ireland, and VI of Scotland. But Holinshed's Chronicles didn't tally with other historical records. For example, most historians have found Nesta married, only once, to Osbern FitzRichard. Nesta's mother was Aldgyth aka Edith of Mercia [d. after 1070]. Aldgyth took as her second husband King Harold II [1022-October 14, 1066] of England. She was the daughter of Aelfgar [d. c. 1062], Earl of Mercia; and the granddaughter of Leofric [d. August 31 or September 30, 1057], Earl of Mercia and husband of Godgifu [fl. 1040-1080], the Lady Godiva of history, legend, and literature.
