My half-brother was Robert David Trueman who went by the name of Robert David Burrus. He was born in 1913 in Vermilion Co, Il. I am looking for his family. He would be 90 now and is likely no longer living. He had two sons and a daughter and they all lived in Florida 10-15 years ago. One son was Robert David Burrus Jr. If anyone can give me any help on locating this family, it would be most appreciated.
