Nope, sure enough he did have some rather harsh times as well, like when his mother and his wife died just a few hours apart, or when his youngest son was shot down as a pilot in WW1 (his oldest son later died of health complications in WW2 shortly after he had been the only general to land with the first attack wave in Normandy, but Roosevelt had been dead for about 25 years by that time), but he didn't loose a son in a train accident.
