Hello, I am looking for any information about my G-Grandfather, Robert Clifton Smith and his parents. He was the son of Catherine Aird (12/22/1865) of Scotland and Robert Smith. Catherine's parents were: James Aird (1836) and his wife, Marion McVake (1841). Robert Clifton was a coalminer in Alabama and died about 1958 of brown lung. He was married to Fannie Clark. Any information would be helpful.
