True name of soldier who lost his brothers was Niland. Two of his brothers died on the invasion day - one served in 82nd airborne and other in 4 infantry div. (it landed on Omaha), third brother died the same week in Burma. Original Ryan`s name was Fritz Niland, and he served in 101st airborne and he was dropped in Normandy (I am not sure but I belive he served in E company - portrayed in Band of Brothers TV show - in Saving Private Ryan Ryan is from that company - and I think that I read about it in the book of S. Ambrose that describes this company). Niland was sent home by the order of general Marschall (chief of staff). So the film is not so far from the history. Of course there were no rescue action and the town was fictional.
