My grandfather, Frank Boyd, was killed in 1917 when a tree fell on the car he was driving. My uncle, Jeff Boyd, and my aunt, Bonnie Boyd, were both badly injured. They were children and my mother, Jean Frank Boyd, was born 6 weeks after this tragedy. Is there any way to find out more about this incident? Any newspaper articles or anything? They lived in Heath, Rockwall County, and were on their way to the state fair in Dallas so I'm not sure where the accident took place.
