I have researched my line well authenticated from William Heugh b.1807 Airth, to Robert Heugh b. July 1760, St Ninians, married Janet Watt at Airth Dec. 1794, to John Heugh b. 6 Nov 1710, m. Janet Gillespie, to Archibald Heugh born c. 1680s we think, married Aelison Brown Falkirk Oct 1709. After that it gets difficult, seems Archibald's father MAY have been the John Heugh baptised 8th August 1665 the son of John Heugh who married Christian Wilson at Stainhouse.
Any help appreciated, I can send you all the research done by myself, Debretts and various Scottish genealogists if it helps.
