My grandfather, William Cockburn, was born in Rosebank, Lugar, Auchinlech Parish, Ayrshire,. on 22 April 1868. His mother and sibs emmigrated to Illinois circa 1885. I have no record of his father, John or mother Agnes Moffat Anderson, who were married in the parish church at Muirkirk on 30 April 1861. Does this ring a bell with anyone? William had four sisters, Agnes, Elizabeth, Martha and Nellie (Clara), and three brothers, Robert, David and John. Many of them ended up in Southern California. I have many family names but very few dates. Can you help?
