Looking for Robert Drybrough Cunynghame born 5 May, 1786 to Parents George Cunynghame and Isabella Drybrough in Linlithgow,WLN, Scotland. His siblings were William Cunynghame born 1789 and Isabella Cunynghame born 1793. In 1807 Robert married Elizabeth Ogilivy in Leith, MLN, Scotland. Robert and Elizabeth had 3 sons George, William and Robert. After the death of his wife Elizabeth, Robert came out to Australia in 1822. In 1823 Robert married the second of his three wives Mary Whalan. I am descendant from Charles Whalan Cunynghame the first of their 4 sons.
Specially looking for other Cunynghame Researchers from Leith, Scotland. Robert and Elizabeth's son George and Grandson were believed to be well known Doctors in Edinburgh.
