A wild guess - but who knows

I can't find the evidence, but maybe there's a connection to;
HISTORY OF SUCCESS
Back in the 1950s, machinist and master die cutter George Smith Sr. tinkered around with race cars and motorcycles in his spare time. His quest to go faster resulted in success and recognition at the drag strip, and ultimately led him and his friend Stanley Stankos to the start S&S Cycle in Blue Island, Ill.
One year later, in 1959, Smith Sr. and wife, Marjorie, whose maiden name was also Smith, bought out Stankos. So instead of Smith and Stankos, S&S then stood for Smith and Smith. Those who knew Marjorie will attest that she knew the business nearly as well as her counterpart.
Brett Smith fondly conveys, "It is a rare example of a husband and wife building a niche manufacturing company in the late 1950s and early 1960s. At a time when women stayed home and raised the kids, my grandmother was here at the shop."
A museum at the S&S facility displays the Smith's original lathe and a photo of the house they mortgaged in order to buy it.
"They disassembled it [the lathe], brought it through a side door and coal chute window, then reassembled it in the basement," says Smith.
In 1969, the couple moved the business to rural Viola where Smith Sr. could also pursue his love of farming.
"S&S got to the point where it was making enough money that my grandparents could leave Blue Island, Ill., come up here [Wisconsin] and support the farming habit," says Smith.
