Marconigrams for the Thayers


On 18 April 1912, Marian Thayer sent a Marconigram from the Carpathia to a woman named Margaret Morris, who was in London at the time. I am wondering, who was Margaret Morris? Was it a sister of Marian or some other relative?

Two Marconigrams were intended for the Thayers, but were never transmitted beyond Camperdown. The first was from someone named Frank McFadden on 16 April, from New York. Who was McFadden; simply a friend of the family?

The second, on 17 April, was from Jus Rich? Who was Mr. Rich, and is "Jus" simply short for "Justin"; I have never heard that name before.

Any help is MUCH-appreciated!
