This is what I have from the Weir family, but I'm afraid the approximated dates are all guesses only:
1 Sir William Weir of Stonebyres, who donated "seven dolours" to the Library of Glasgow University in 1631 and who served on the Committee of War for Lanark, 1644, 1647-48.By his wife he was the father of: 2 Katherine (Catherine) Weir born circa 1649 + Alexander Fergusson b. c 1645 d. after 1700, son of Alexander Fergusson & Margaret Sydserf; grandson of John Fergusson & Helen Kennedy.Issue: 3 John Fergusson(b. c1670-75) +1 Margaret Crawford +2 Elizabeth Boswell 3 William Fergusson (b. circa 1678) + Agnes Kennedy 3 Alexander Fergusson(b. c1680)
My interest in the Fergussons is ROBERT (Rob, Rab)Fergusson "of Edinburgh" in 1653 (or c1670-80), born probably about 1630-1660.His daughter Jane(t) Fergusson married John Wier (Weir) in 1653 or c1670 (depending on which version is correct, but could have been as late as 1690-1720!), married by "an outlawed meenister" (Presbyterian), and John Wier's "gentry kin were much put out" by it, according to the book "Ten Tribes of Wier in America" by William S. Wier.
They had a son: James Wier born in 1683, supposedly, (but COULD be as late as 1720) who married Margaret Agnes O'Marra or O'Malla, "of an old Roman Catholic family ruined by the religious intolerances of the times,"and had a son: Thomas Wier who married circa 1760 Elizabeth Faulkner of Londonderry.The family history stated Thomas was born 1708 and his father was born in 1683, but I suspect these may have been guesses, since the full dates were not shown.Thomas Wier (b. 1730-40?) and Elizabeth Faulkner Wier's first children were born apparently circa 1760 and the youngest son born 1769.
