I hope this helps you.I have alot of old family records and photos from the Cunningham line in my family.One letter is from my gr-gr aunt Jessie Duncan Cunningham writing home to her brother in Scotland, Peter Girvan Cunningham (my gr-gr grandfather).She is in Soldier River (?) United States and is dated April 9th, 1876.It is a long letter that really expresses how much she misses her family and Scotland.She is married to Peter Dunlop and mentions children one in particular Robert who did not take a good "card" (Photo).She also mentions that Peter's brother John who must be in Soldier River also died that year in March.He had a wife from Wales and five children. this is a real personal letter that expresses how much she misses her family and her homeland of Scotland.
My Aunt Jessie Duncan Cunningham married Peter Young Dunlop in 1866 in Ayr, Scotland.
I do not have alot of info on the Dunlop family as the connection in though marriage but I do have some on the Cunningham line which should be useful.I also have some photos that are from that time that have not been identified.
