I have just discovered that my 4th great grandparents, Alexander McLeod and Flora McLeod were born in Scotland. I know that they were not married to each other when they came to America. I found a marriage record that shows that they married on May 10, 1830. Her maiden name was Flora McNish.
He was born about 1801 and she was born about 1806-1807.
I have not been able to find the family in any US Census records before 1830. All of their children were born in Cumberland County,NC.
On the 1850 US Census, it shows their oldest child being 19 years old which would have put him being born about 1831 which falls in line with their marriage in May of 1830.
How do I figure out from where in Scotland they are from and about what time they migrated to America?
