Kim, "Thank You" for your time and generosity on searching for the Cunningham data. I have all of it that has occurred in the USA from the time of the arrival of Andrew in 1834. His brother John died on 25 Sept, 1838 in Cass Co, IL so that is why you could not find him on censuses.
Actually, their father, James, came as a soldier for King George just prior to our Revolutionary War. He changed sides and joined the US militia. He stayed for a abt 2 yrs then returned to Scotland where he married Marion Wright. Her name comes down through the family histories so she probably is the B. Wright who ma James Cunningham in 1782. He was a baker in Bonnington, Midlothian and owned a lot of real estate there. It is said the towns people called him 'Auld Laird'. He and Marion Wright supposedly had 3 dghts and 5 sons.
Because of the repetition of given names it is hard to sort the children of the various members of this Cunningham ancestral family. James and Marion had a son, Charles, that was a representative of the British govt and died in the Black Sea area of Russia while on duty there. Son Archibald supposedly died in Scotland; sons, Andrew, George, and John removed to Cass Co IL. Dght Jeanette supposedly married a man named Shain and lived in England, Margaret ma Henry Blair, and Mary married __ Russell. I have not been able to confirm his death but supposedly the father ,James Cunningham, died in 1845.
I also have thought that the marriage record of John Cunningham to HELEN Taylor on 22 May, 1823 is most surely the John that removed to Cass Co IL. Do you know if there was any other info on that marriage that would prove it was the John of my research?
I am going to print off what you have posted so I can compare it with the info that I have.
Again, MUCH APPRECIATION for your assistance. Bettye in California
