Members of the group contacted the Evening Express after seeing the story.
David Leslie, now 69, and a dad-of-two and grandad-of-four, described the article as a “cold blast from the past”.
The former architect said: “We are all retired and still alive – and yes I did marry my girlfriend Leslie.”
David and Leslie Leslie now stay next door to Leslie Castle, Leslie, near Insch.
Michael and Roddy Stuart also got in touch by e-mail.
It took Roddy and the rest of the group the afternoon and most of the evening of Wednesday, January 2, 1963, to build it.
Michael, 71, a retired engineer in Westhill, said: “I was very surprised to hear about the snowman after all these years.
“I never imagined people would be looking at it across a continent or that I would be hearing it again now.”
In her original letter to Roddy, Victoria wrote: “Dear Roddy, I thought you might be happy to see how far your talents have reached in this wonderful world of ours.”
