Robert Bain provided valuable information on the Meigle Wighton's Generation 4 family (Janet Wighton and siblings) through his own research of the Smith family line - the descendants of Janet Wighton and her 5th child, Anne Fleeming Lindsay. Here's a brief outline of just one part of that lineage - the line extending to his partner Eilidh Mary Smith, born in 1976. I have shown the line all the way back to John Wighton in Meigle.

John Wighton (b. 1708, m. Helen Mill, 1734, 3 children, d. 1758, lived in Meigle)

William Wighton (b. 1735, had 1 child with Marjory Anderson, d.?, lived in Meigle)

Thomas Wighton (b. 1760, m. Elizabeth Taylor, 1789, 7 children, d.?, lived in High Keillor)

Janet Wighton (b. 1791, m. William Lindsay, 1812, 9 children, d. 1882, lived in High Keillor)

Anne Fleeming Lindsay (b. 1821, m. James Smith, 1849, 4 children, d. 1884, lived in various places)

James Smith (b. 1853, m. Marjory Law, 1881, 3 children, d. 1885, lived in Perthshire)

Robert Smith (b. 1883, m. Isabella Cameron, 1914, 6 children, d. 1953, lived in Tulloch)

Mary Marjory Smith (b. 1916, 2 children while unmarried)

Edward Smith (b. 1945, m. Flora Elizabeth MacPherson, 1968, 3 children)

Eilidh Mary Smith (b. 1976)
