Stengel, Mrs Annie May	5	5	5.00

Following the disaster, Mrs. Stengel wrote the following letter to fellow survivor Archibald Gracie (reprinted in On Board RMS Titanic, page 403):
  "As I stepped into the lifeboat an officer in charge said: “No more; the boat is full.” My husband stepped back, obeying the order. As the boat was being lowered, four men deliberately jumped into it. One of them was a Hebrew doctor - another was his brother. This was done at the risk of the lives of all of us in the boat. The two companions of this man who did this were the ones who were later transferred to boat No. 7, to which we were tied. He weighed about 250 pounds and wore two life preservers. These men who jumped in struck me and a little child. I was rendered unconscious and two of my ribs were very badly dislocated. With this exception there was absolutely no confusion and no disorder in the loading of our boat."

Though Mrs. Stengel doesn't specifically state the number of her boat, her description fits #5 perfectly.  The "Hebrew doctor" jumping in was Dr. Henry Frauenthal.  And that her boat had tied to #7.
