Apologies Monica and Rosie. I didn't get a notification so wasn't aware of your replies. Sorry!
No, I have never worked out the nephew Patrick on the 1861 census. It's a mystery! However, I have just discovered a sister for my Patrick. A long story but it emerged after researching the person who purchased a lair where several Dunning descendants lie buried. It's taken 5 years to work out his identity. His mother was Jane Dunning. This Patrick could be her illegitimate son or the son of another sibling I haven't discovered yet. I have no other Patricks in my tree born around that time. Patrick had a son Peter, who could also be a Patrick but he was born about 1856.
I can't trace the census record you refer to for Hugh McLean living with Matthew Dunning. Are you able to direct me to finding it as he is not in my tree. I am very interested as his parents are recorded as John Dunning farmer and Margaret Dunnan but John Dunning's wife died in 1866. Or I have misunderstoon and it was Hugh McLean's mother Margaret who had parents John and Margaret. If Margaret was the daughter of John and Margaret, then I've missed her completely.
The 1861 St. Quivox census for Margaret sounds promising too.
Very much appreciated.
