There is a popular - though disputed - story that Americans started calling coffee "a cup of Joe" when Secretary of the Navy Josephus Daniels got rid of the rum ration on U.S. ships. Once Joe eliminated the rum ration, the strongest drink you could get on board was coffee. Hence, "cup of Joe". Is it true? Who knows? But I like it.
"Morgan" is also used to refer to DNA segments, named after Thomas Hunt Morgan. I would say it is as much a "segment" as a gene is. https://isogg.org/wiki/CentiMorgan
