I have only recently (yesterday) discovered the parent of one of my ancestors was David Kinghorn (perhaps m. 1823 to Frances VERT) and had a daughter Cathering b. about 1825 Scotland. She later emigrated to Australia (married a WOOD in 1848 ?)
None of my info is completely solid at this point relating to the Kinghorns as i am working from records available in Australia.
Would love to know if we connect. Good luck with your research and i look forward to hearing from you.
