Hi Caroline, If he was related, it wasn't closely, since he was a New Yorker and they were Canadian. My impression has always been that Mrs. Astor's husband came from a very hoity-toity Society family; and that the Dicks, though obviously well-to-do, were of more modest origins. This is only my impression; somebody else around here might know better.
As an aside, I went to summer camp as a child with William K. Dick's grandson from his second marriage (i.e. not Mrs. Astor's grandson). This boy was the only other kid I've ever come across who was as much, if not more, of a Titanic enthusiast than I was.
There are quite a few articles discussing Mr. Dick, including his obituary, linked to Mrs. Astor's biographical page. They bear out Brian's impression that he was from a wealthy, socially well-connected, family.
WM. K. DICK MARRIES MRS. VIRGINIA CONNER --- Chairman of the National Sugar Refining Co. Weds in Akron --- Word has been received here of the marriage of Mrs. Virginia Keniston Conner, daughter of Mr. and Mrs. Edwin S. Conner of this city, to William K. Dick of this city and Alden Winden Farm, Islip, L. I., which took place in Akron, Ohio, yesterday afternoon in the presence of relatives. They will live in Islip and New York.
The bride attended the University of Akron. She studied at the Cleveland School of Fine Arts, was graduated from the Paris branch of the New York School of Fine and Applied Arts and has also studied in New York where she is an interior designer. Her previous marriage to Willoughby Brazeau was terminated by divorce last year.
Mr. Dick is a son of the late Mr. and Mrs. J. Henry Dick and a grandson of the late William Dick, prominent in the founding of the sugar industry in this country. Mr. Dick has two sons by his former wife, the late Mrs. Madeline Force Dick. They are William F. Dick, who married Miss Virginia French on Dec. 17, and John Henry Dick.
The bridegroom is chairman of the executive committee of the National Sugar Refining Company and director of several large corporations. He is a member of the Brook, Racquet and Tennis, Southside, National Golf Links and Turf and Field Clubs and the Downtown Association.
[MAB Note: After Mr. Dick's death, Ms. Conner married Frederick S. Moseley, Jr., and was still married to him when he died in 1972, according to his obituary. The last reference I have to her at the moment is that her name appeared in a display ad listing of designers that appeared in The New York Times on 30 September 1979.]
