Anecdotal but I grew up in in Hingham, MA that has one of the oldest cemeteries in the country. I used to walk through quite a bit and there was lots of what I am assuming was family plots that would have smaller headstones that would say "baby", and or "son/daughter", etc. Seemed so odd to me. I could only assume these families died at the same time from something tragic. But there was lots of plots that were like that.

You should have corrected them because they were flat out wrong. They are named after the machinist who ran the machine that first created them.

You are WRONG

No. They are named after the machinist (who ran the machine) that was the first to be used to make Jimmies. Look up the story and please stop spreading this misconception

No
