Call sign history - AB4UG

Inspired by Alan/W2AEW's most recent video, Ham Radio call sign history, and my QSL card quest and some Twitter posts by W5RST and W0EA, I thought I'd dig into the past of my current call sign, AB4UG. I don't expect it to be as interesting or storied as some other call signs, but it will be interesting to see what I can find out.

I knew AB4UG had been used previously by someone else because of looking it up in the AE7Q database as well as the FCC ULS database. Both list only one previous user for AB4UG from KY, issued 1990-03-13 and expired in 2000-03-13. The AE7Q database suggests a pre-ULS history, but no further details.

A Google search for AB4UG shows mostly my stuff or references to me, but then a couple pages down is a page listing some SK's (silent keys) for the Southern Ohio Amateur Radio Association where the previous AB4UG is listed.
